MAX14852GWE+

MAX14852GWE+ - 2.75kV Isolated RS-485/RS-422 Transceiver | Maxim Integrated

The Maxim Integrated (now Analog Devices) MAX14852GWE+ is a 2.75kVRMS isolated, full-duplex RS-485/RS-422 transceiver housed in a 16-pin wide-body SOIC (WSOIC) package. It supports data rates of 500 kbps (low-speed mode) and 25 Mbps (high-speed mode), operates from a 1.71V to 5.5V supply on both the UART and cable-side domains, and provides 35 kV ESD protection (HBM) on the bus pins per the Maxim datasheet. An isolated RS-485 transceiver is a bus interface IC that combines a standard differential line transceiver with on-chip galvanic isolation. Isolation breaks ground loops, eliminates common-mode voltage damage, and rejects large ground-potential differences between system nodes. Within a typical industrial system, the MAX14852 sits between a microcontroller UART and the RS-485 bus, sitting in the signal-chain layer between the controller SoC and the field wiring. Key features of the MAX14852GWE+ include integrated transformer-driver isolation (no external transformers or optocouplers required), 1 driver / 1 receiver full-duplex configuration, true fail-safe receiver inputs, hot-swap capability on the bus side, and a low supply current that suits battery-backed or always-on industrial nodes. The wide-body SOIC package provides the minimum 8 mm of creepage/clearance required for 2.75 kVRMS reinforced isolation per IEC 60950 / IEC 62368. Technically, the MAX14852 uses Maxim's proprietary iso-loop isolation technology to embed an isolation barrier and DC-DC drive directly inside the IC, eliminating the need for an external isolated power supply on the cable side. The 2.75 kVRMS rating is verified for 60 seconds and the part is rated for -40 °C to +105 °C operation, suitable for outdoor cabinet and industrial-control environments. Typical applications include isolated Modbus RTU links in PLCs, RS-485 repeaters/bridges, solar inverter monitoring, building automation gateways, and any industrial node requiring robust ground isolation. Compared with optocoupler-plus-isolated-DC/DC discrete implementations, the MAX14852 reduces BOM count, PCB area, and design time. When designing with this device, allocate the WSOIC-16 footprint on the PCB with adequate clearance under the package to preserve the 2.75 kV rating, and bypass both VDD pins with 0.1 µF + 10 µF capacitors placed within a few millimeters of the pins. Note that the MAX14852GWE+ and MAX14854GWE+ differ in data-rate grade (500 kbps/25 Mbps vs 25 Mbps fixed). This page synthesizes drop-in alternatives in the WSOIC-16 package, distributor pricing tiers, and practical PCB layout/design notes that go beyond what is shown on Maxim/Analog Devices product pages.

MAX14854GWE+

MAX14854GWE+ - 25Mbps Isolated RS-485/RS-422 | Analog Devices

The Analog Devices MAX14854GWE+ is a 25Mbps isolated full-duplex RS-485/RS-422 transceiver with 2.75kV RMS galvanic isolation, 35kV ESD protection, and a 16-pin wide SOIC package. It supports a 1.71V to 5.5V supply range and integrates one driver and one receiver for robust point-to-point or multipoint serial links. The isolation barrier separates the cable-side driver and receiver from the UART-side circuitry. An isolated RS-485/RS-422 transceiver is an interface IC that translates logic-level signals into differential cable signals while providing galvanic isolation between equipment domains. Galvanic isolation breaks ground loops, reduces common-mode noise, and protects low-voltage UART electronics from cable-side transients. This makes the MAX14854GWE+ suitable for industrial communication, test equipment, building controls, and systems where the host and cable grounds may be at different potentials. The device supports operation from 1.71V to 5.5V, data rates up to 25Mbps in the high-speed mode, and lower-rate operation down to 500kbps according to the manufacturer product description. Its full-duplex architecture supports separate transmit and receive paths, while the integrated isolation barrier provides 2750V RMS for 60 seconds. The cable interface includes ±35kV ESD protection, a significant advantage in connector environments where electrostatic discharge is a recurring threat. The MAX14854 family is designed for robust differential serial communication where isolated voltage levels and high data throughput are both important. The MAX14854GWE+ combines an integrated isolation barrier with RS-485/RS-422 driver and receiver functions, reducing the number of external isolation components required. Its wide-body SOIC package is intended for surface-mount industrial equipment and is compatible with automated assembly. Typical applications include industrial RS-485 links, isolated UART bridges, factory equipment interfaces, building automation, instrumentation, and communications between controllers and remote sensors. The full-duplex configuration is especially useful when simultaneous transmit and receive operation is required, while the isolation rating supports dependable communication across equipment boundaries. Designers should verify supply voltage, baud-rate mode, termination, fail-safe biasing, isolation requirements, and cable-side protection before layout. Place the isolation-related components and differential traces according to the manufacturer datasheet, and keep the logic-side and cable-side ground domains physically separated. The MAX14854GWE+ is an active, leaded surface-mount device identified by the GWE+ ordering suffix.

MAX14882AWE

MAX14882AWE - 5kVRMS Isolated CAN Transceiver, 1Mbps, 16-SOIC

The Analog Devices (formerly Maxim Integrated) MAX14882AWE is a 5kVRMS galvanically-isolated high-speed CAN transceiver housed in a 16-pin wide-body SOIC (WSOIC) package. It operates at data rates up to 1Mbps and provides 5000VRMS (60s) of isolation between the CAN-protocol controller-side (TXD, RXD) and the physical bus-side wires (CANH, CANL), integrating the isolation barrier, an isolated DC-DC transformer driver, and an LDO for bus-side power. A CAN transceiver is a physical-layer interface IC that translates the differential CAN protocol from a microcontroller into the robust voltage levels required on a CAN bus, while providing protection against ground loops, common-mode transients, and bus faults. Isolated CAN transceivers additionally place a galvanic barrier between the controller and the bus, eliminating ground-potential differences and surge propagation in industrial environments. The MAX14882AWE falls in the hierarchy: CAN transceiver -> automotive/industrial bus interface IC -> interface IC -> integrated circuit. Key features include a ±25V receiver common-mode input range (exceeding the ISO 11898-2 requirement of -2V to +7V), ±54V fault-tolerant CANH/CANL outputs, and ±15kV HBM ESD protection on the bus-side pins to GNDB. The controller-side operates from VDDA = 3.0V to 5.5V, while the bus-side runs from VDDB = 4.5V to 5.5V with an integrated transformer driver that supports an external transformer for isolated supply rails. Operating temperature spans -40°C to +125°C. The device supports a low-power standby mode for remote-wakeup and an integrated POL (polarity swap) feature that swaps CANH and CANL functions to correct cross-wired cables via software. The wide-body SOIC package provides 8mm of creepage and clearance, satisfying IEC 60950 and IEC 62368 reinforced insulation requirements for industrial and renewable energy installations. Typical applications include isolated CAN nodes in solar inverters, industrial PLC backplanes, electric vehicle battery management systems (BMS), and any industrial network requiring robust galvanic isolation between the controller MCU and the noisy CAN bus cable plant. When designing with the MAX14882AWE, the external transformer (e.g., a 1:1.3 or 1:1 turns ratio miniature transformer) is the critical BOM item that determines the isolated bus-side rail voltage and overall efficiency. PCB layout must maintain 8mm creepage across the WSOIC body and avoid copper traces under the package to preserve the reinforced insulation barrier. This page synthesizes drop-in alternatives, distributor pricing as of 2026-10-16, design notes, and a side-by-side comparison versus MAX14882 family variants and competing isolated CAN transceivers not found in the manufacturer datasheet alone.

MAX14882AWE+T

MAX14882AWE+T - 5kVRMS Isolated CAN Transceiver | Analog Devices

The Analog Devices (formerly Maxim Integrated) MAX14882AWE+T is a 5kVRMS isolated high-speed CAN transceiver that integrates galvanic isolation between the CAN-protocol controller side (TXD, RXD) and the physical CAN bus wires (CANH, CANL), delivering 1Mbps data rate over a 3.0V to 5.5V controller-side supply and 4.5V to 5.5V bus-side supply in a 16-pin wide-body SOIC (W SOIC) package with 8mm of creepage and clearance. What is an isolated CAN transceiver? A CAN (Controller Area Network) transceiver is the physical-layer interface between a digital CAN protocol controller and the differential CAN bus cables. An "isolated" variant adds a galvanic isolation barrier (here, 5kVRMS) that breaks ground loops, rejects common-mode transients, and protects low-voltage microcontrollers from high-voltage faults on the industrial CAN bus. The MAX14882 sits in the product hierarchy: CAN transceiver -> automotive/industrial transceiver -> isolated interface IC -> power management and signal conditioning IC family. Key features include a ±25V receiver input common-mode range (exceeding the ISO 11898-2 requirement of -2V to +7V), ±54V fault tolerance on CANH/CANL, ±15kV HBM ESD protection on bus-side pins to GNDB, an integrated transformer driver with LDO that supplies VDDB from an external transformer, and a POL (polarity) pin that swaps CANH/CANL functions for software correction of cross-wired bus cables. The integrated isolation eliminates the need for a discrete digital isolator plus an external isolated DC/DC supply, reducing BOM count and PCB footprint by roughly 50%. Typical applications include industrial automation networks (CANopen, DeviceNet), building automation HVAC controllers, solar inverter inter-module communication, electric vehicle battery management systems (CAN-FD ready), and any microcontroller-to-bus interface requiring robust galvanic isolation in harsh electrical environments. When designing with this part, place decoupling capacitors (typically 100nF plus 10µF) on both VDDA and VDDB as close to the IC as possible, and route the external transformer primary traces symmetrically. The integrated LDO can source up to 300mA for auxiliary circuits after supplying the internal 130mA MAX14882 load, but derate at high bus-side temperatures.

MAX148ACAP+T

MAX148ACAP+T - 10-Bit 8-Ch SAR ADC 133ksps 20-SSOP | Maxim

The Maxim Integrated (Analog Devices) MAX148ACAP+T is a 10-bit, 8-channel, low-power successive-approximation analog-to-digital converter (SAR ADC) with a 133 ksps sampling rate in a 20-pin SSOP package. The "A" suffix denotes the extended sampling-rate grade (133 ksps vs 90 ksps for the MAX148B/C grades), and the "CAP" suffix denotes the 20-pin SSOP with commercial temperature grade (0C to +70C). The "+T" suffix indicates Tape & Reel packaging. A SAR ADC is a type of analog-to-digital converter that uses a binary search through each bit to approximate the input voltage, performing one conversion per N clock cycles (N = resolution in bits). SAR ADCs excel at medium-speed, medium-resolution conversions with deterministic latency, no pipeline delay, and very low power consumption, which is why they dominate battery-powered industrial sensor, panel-meter, and data-acquisition applications. Key features of the MAX148ACAP+T include a single +2.7V to +5.25V supply (typically +5V), an 8-channel single-ended or 4-channel differential analog input multiplexer with high-bandwidth track/hold, an SPI/QSPI/MICROWIRE-compatible serial interface, hardware and software shutdown modes (less than 10 microA quiescent current in shutdown), and an internal 4.096V or external reference option. The MAX148 provides 0 to +5V unipolar input range with the internal reference. Architecture: the chip combines a track/hold front-end, an 8-to-1 analog mux, a charge-redistribution SAR core, and an internal reference. The internal reference is selectable to either 4.096V (for 0-5V unipolar input, MAX148) or 2.048V (for 0-2.5V unipolar input). The serial interface can clock up to 2.1 MHz, supporting full-speed conversions at the 133 ksps maximum rate. Typical applications include 4-20mA loop-powered industrial sensors, panel meters and digital multimeters, data-acquisition cards, portable instrumentation, and battery monitoring systems. Designers choose this part for its combination of 8 channels, low power, and small SSOP footprint. The trade-off versus higher-resolution ADCs (12, 14, 16-bit) is dynamic range. The MAX148 offers 10-bit resolution (about 60 dB SNR), so designs requiring better than 0.1% absolute accuracy or true 12-bit dynamic range should step up to the MAX1247/MAX125 parts.

MAX148AEPP+

MAX148AEPP+ - 10-Bit 8-Ch 133ksps 5.25V Precision ADC | Maxim Integrated

The Maxim Integrated MAX148AEPP+ is a 10-bit, 8-channel, low-power serial-interface analog-to-digital converter (ADC) that combines an 8-channel analog multiplexer, a high-bandwidth track-and-hold, and a serial interface in a single 20-pin PDIP package. It operates from a single +2.7V to +5.25V supply, accepts up to 8 single-ended or 4 differential analog inputs, and delivers up to 133 ksps throughput while consuming only 1.2 mA (typ) at full sampling rate. What is a SAR ADC? A successive-approximation-register (SAR) analog-to-digital converter is a precision data-conversion architecture that builds the output code bit-by-bit using an internal DAC and comparator. SAR ADCs sit in the broader hierarchy of data converters (ADC) -> mixed-signal ICs -> signal chain ICs -> power management and analog semiconductors. They are favored for medium-speed, medium-resolution applications where deterministic latency, low power, and small package size matter more than the very high sampling rates of pipelined or sigma-delta ADCs. Key features include ±1 LSB INL and DNL (max) over the industrial -40°C to +85°C range, a hardware SHDN pin plus software-selectable power-down that drops supply current to under 10 µA between conversions, an external serial clock up to 2 MHz (SPI/QSPI/MICROWIRE compatible), and a flexible reference input accepting ratiometric conversions or an external 2.5V/4.096V reference. The internal MUX-S/H-ADC chain provides true 8-channel scanning with sequential or on-demand channel selection, and automatic shutdown at end-of-conversion further reduces system power in battery-driven designs. The MAX148 uses a charge-redistribution DAC core with an auto-calibrated comparator and a synchronous serial output that streams the conversion result MSB-first. The serial interface supports daisy-chaining multiple devices (CS line selects the active device), allowing multi-channel expansion without consuming additional microcontroller pins. The wide supply range and reference flexibility make it equally at home on a 3.3V logic rail or a 5V analog rail. Typical applications include portable data logging, 4-20 mA industrial sensor multiplexing, multi-cell battery monitoring, HVAC thermostat analog front ends, panel meters and digital multimeters, and distributed-control / SCADA analog input modules. The combination of 8-channel input mux, SPI interface, and 1.2 mA operating current also suits handheld medical and instrumentation designs where both channel density and battery life are critical. When designing with this device, choose an external reference (e.g. MAX6125 or REF02) when absolute accuracy is required; for ratiometric ratiometric bridge or thermistor measurements the supply can serve as the reference. Place a 0.1 µF decoupling capacitor directly at VDD and a 10 µF bulk capacitor at the analog supply pin to suppress digital switching noise that would otherwise couple into the SAR comparator. This page synthesizes distributor pricing (Mouser/DigiKey), cross-reference alternatives from the Maxim MAX148 family, and PCB-level design guidance that goes beyond the manufacturer datasheet, helping engineers evaluate a drop-in upgrade path quickly.

MAX14931AASE+T - 4-Ch 1Mbps 2.75kVrms Digital Isolator | ADI

The Analog Devices (formerly Maxim Integrated) MAX14931AASE+T is a 4-channel, 2.75kVRMS digital isolator in a 16-pin wide-body SOIC package, supporting 1 Mbps data rate with a typical CMTI of 25 kV/µs. The device transfers digital signals across an isolation barrier using Maxim's proprietary process technology, and the 3/1 unidirectional channel configuration makes it well suited to SPI, RS-232, RS-485, and general-purpose digital I/O isolation. A digital isolator is a semiconductor device that uses an internal isolation barrier - typically a capacitive, magnetic, or optical coupling structure - to transmit logic-level signals between two galvanically isolated voltage domains while blocking DC and low-frequency currents. Digital isolators replace optocouplers in modern designs and are classified within the broader signal-chain and interface-IC family. They are key building blocks for reinforced insulation, functional safety, and high-voltage system partitioning. Key features of the MAX14931AASE+T include 2750 Vrms withstand voltage, 1 Mbps guaranteed data rate across -40 °C to +125 °C, 25 kV/µs typical common-mode transient immunity, low propagation delay of 42.9 ns, and 1.71 V minimum supply voltage. The wide-body SOIC-16 package provides the required creepage and clearance for reinforced isolation at 2.75 kVRMS, simplifying PCB layout for industrial bus isolation. Internally, the MAX14931AASE+T uses Maxim's proprietary CMOS isolation technology with integrated dc-dc converter control on the secondary side for optional isolated power. Each of the four channels is unidirectional, three in one direction and one in the reverse direction, matching typical SPI / UART peripheral-interface signalling patterns without requiring external direction-control logic. Typical applications include isolated SPI interfaces for industrial PLCs, isolated RS-485 transceivers in factory automation, isolated gate-drive signal conditioning for motor drives, and medical device patient-isolated data links. The wide operating temperature range supports both industrial and automotive-grade designs. When designing with this device, follow the SOIC-16 wide-body creepage and clearance guidelines: maintain at least 8 mm of PCB spacing under the package body and avoid routing copper traces between pins to preserve the 2.75 kVRMS rating. Decouple both VDD pins with 0.1 µF low-ESR ceramic capacitors placed within 2 mm of the supply pins.

MAX14931BAWE+T

MAX14931BAWE+T - 4-Ch 2.75kVrms Digital Isolator | Analog Devices

The Analog Devices (formerly Maxim Integrated) MAX14931BAWE+T is a 4-channel, 2.75 kVrms general-purpose digital isolator housed in a 16-pin wide-body SOIC (WSOIC-16) package with 3/1 channel direction configuration. It supports data rates up to 25 Mbps and delivers typical common-mode transient immunity (CMTI) of 25 kV/µs, transferring digital signals across an isolation barrier using the proprietary process technology that integrates a single-ended CMOS or LVCMOS interface on each side. A digital isolator is a semiconductor device that uses galvanic isolation (typically via on-chip transformers, capacitive barriers, or optocouplers) to allow high-speed digital communication between two domains that sit at very different ground potentials or that must remain safety-isolated. Digital isolators -> isolators -> interface ICs -> signal conditioning ICs -> semiconductors is the taxonomy hierarchy. Compared with legacy optocouplers, CMOS-based digital isolators offer faster data rates, tighter channel-to-channel matching, lower power consumption, and CMTI performance two to three orders of magnitude higher. Key features of the MAX14931BAWE+T include a 2.75 kVrms withstand voltage per UL 1577, default output state options (high or low) across the MAX14930/MAX14931/MAX14932 family, 1.71 V to 5.5 V wide supply range on both sides, and an operating temperature range of -40 °C to +125 °C. The integrated refresh circuit maintains stable output levels when input signals remain static for long durations, eliminating the input-signal minimum-rate constraints common to many AC-coupled isolators. The MAX14931BAWE+T uses Maxim's proprietary process technology that embeds an isolation barrier directly inside the die-package stack-up. This monolithically integrated approach reduces channel-to-channel skew to under 4 ns and provides a low pulse-width distortion around 5 ns, preserving signal integrity at the 25 Mbps maximum data rate even in motor-drive and industrial-servo environments where dv/dt transients easily exceed 10 kV/µs. Typical applications include isolated RS-485/RS-422 interfaces, isolated SPI or I2C data links between MCU and high-voltage drivers, industrial fieldbus isolation (Profibus, Modbus, CAN), isolated gate-driver signal paths for IGBT and SiC power stages, and medical equipment patient-isolated signal acquisition. The wide 1.71 V to 5.5 V supply range lets the same part serve 1.8 V, 2.5 V, 3.3 V, and 5 V logic rails without level-shifters. When designing with this device, place 0.1 µF decoupling capacitors as close as possible to each VDD pin on both primary and secondary sides; for optimal CMTI performance, route the isolator away from fast-switching traces, and add a stitching capacitance between the two ground domains to shunt common-mode currents. The default output state (A/B/C/D suffix) must be chosen to match the system fail-safe polarity required by downstream logic.

MAX14931DASE+T

MAX14931DASE+T - 4-Ch 2.75kVrms Digital Isolator, 1Mbps | ADI

The Analog Devices (formerly Maxim Integrated) MAX14931DASE+T is a 4-channel, 2.75 kVrms digital isolator with a maximum data rate of 1 Mbps and 25 kV/us (typical) CMTI, housed in a 16-pin wide-body SOIC package. The device provides galvanic isolation between circuits using Maxim's proprietary process technology, eliminating the need for external isolation components. What is a digital isolator? A digital isolator is an integrated circuit that transfers digital signals across an isolation barrier using capacitive, inductive (transformer), or optical coupling while blocking high voltages and transients. Digital isolators replace optocouplers in modern designs, offering higher speed, lower power consumption, better CMTI, and longer operational life. They sit in the signal chain hierarchy of interface IC -> isolator -> digital isolator -> quad-channel digital isolator, providing functional safety and ground isolation in industrial, medical, and renewable-energy systems. Key specifications include 2.75 kVrms isolation voltage rating per UL 1577, 1 Mbps maximum data rate across four unidirectional channels (3-in/1-out configuration in the MAX14931DASE variant), 25 kV/us typical common-mode transient immunity (CMTI), and a wide 1.71 V to 5.5 V supply range on both sides. The device operates across the -40 C to +125 C industrial temperature range and consumes under 3 mA per channel at 1 Mbps. The wide-body SOIC-16 footprint provides the required creepage and clearance for reinforced insulation at 2.75 kVrms. The MAX14931DASE+T architecture uses capacitive isolation with differential signaling across the isolation barrier and integrated refresh circuitry on the secondary side, achieving deterministic timing with under 50 ns propagation delay. This topology avoids the aging and CTR-degradation mechanisms of optocouplers, providing stable performance over the device's lifetime. Typical applications include isolated SPI/RS-232/RS-485 interfaces, industrial fieldbus isolation (Modbus, Profibus), PLC digital I/O modules, isolated gate drivers for motor control and solar inverters, medical device signal isolation per IEC 60601-1, and battery management system (BMS) communications in electric vehicles. The MAX14931 variant (3-in/1-out channel direction) suits SPI-style clock/SS/MOSI/MISO isolation where the host side has three inputs and one output. When designing with the MAX14931DASE+T, place 0.1 uF bypass capacitors as close as possible to each VDD pin and ensure adequate creepage on the PCB (at least 8 mm for 2.75 kVrms reinforced insulation per IEC 60730-1). The EN pin controls the output enable state and should be tied high for normal operation or left open if unused.

MAX14933AWE+

MAX14933AWE+ - 2-Ch 2.75kVrms I2C Digital Isolator | ADI/Maxim

The Analog Devices (formerly Maxim Integrated) MAX14933AWE+ is a two-channel, 2.75kVrms I2C digital isolator that uses proprietary process technology to galvanically isolate two bidirectional open-drain channels in a 16-pin wide-body SOIC package (0.295"/7.50mm). It supports data rates up to 2 Mbps and tolerates ambient temperatures up to +125°C, with a typical common-mode transient immunity (CMTI) of 25 kV/us. Per the ADI MAX14933 datasheet, this part targets I2C/SMBus applications where the bus must cross an isolation barrier between two different power domains. A digital isolator is a semiconductor device that transmits logic-level signals across a galvanic isolation barrier (typically a high-voltage capacitor or transformer inside an IC package) while blocking DC and low-frequency AC between input and output. Digital isolators (and their ancestors, optocouplers) belong to the signal-isolation family, which also includes isolated gate drivers and isolated ADCs. Compared to optocouplers, CMOS digital isolators offer 10x faster data rates, 5-10x lower power consumption, tighter CMTI, and no LED-aging concerns. The MAX14933 family specifically targets I2C/SMBus, where both clock and data lines are bidirectional and open-drain, requiring unique bidirectional channel design. Key features of the MAX14933AWE+ include 2.75kVrms isolation rating, two bidirectional open-drain channels suitable for SDA/SCL, 2 Mbps data rate, 3.0V to 5.5V supply range on both sides, 25 kV/us typical CMTI, and integrated hot-swap friendly architecture for cards that plug into a live backplane. The device replaces discrete optocoupler-plus-logic solutions with a single CMOS IC, simplifying PCB layout and reducing BOM count in isolated I2C designs. The MAX14933 employs proprietary CMOS isolation technology that embeds the isolation barrier on-chip rather than relying on a separate transformer or LED. The two bidirectional channels each contain edge-detection and channel-reversal logic so that the open-drain I2C signal can flow from side-A to side-B and back without external direction-control circuitry. This architecture delivers the speed and CMTI of modern digital isolators while preserving the bidirectional open-drain behavior required by the I2C specification. Typical applications include isolated I2C communication between microcontrollers and sensors in industrial automation, isolated SMBus interface to hot-swap-able power supplies, isolated EEPROM or temperature-sensor readouts in patient monitors, battery-management I2C buses in 400V/800V EV battery packs, and isolated GPIO expansion over I2C backplanes. The wide-body SOIC-16 (7.50mm) package provides the required 8mm creepage/clearance for 2.75kVrms reinforced isolation. When designing with this part, allocate the wide-body SOIC-16 footprint carefully - the 7.50mm body width is required to meet the 2.75kVrms creepage and clearance, and substituting a narrow-body SOIC-16 will violate safety distances. Both sides need a local 3.0V-5.5V supply with a 0.1uF decoupling capacitor close to each VDD pin, and SDA/SCL pull-up resistors must be placed on the side that drives each line low. This page combines distributor pricing, drop-in alternatives in the same SOIC-16 footprint, and practical design notes that supplement the manufacturer datasheet.

MAX149BMAP/PR

MAX149BMAP/PR - 10-Bit 8-Ch 133ksps SAR ADC | Maxim Integrated

The Maxim Integrated (Analog Devices) MAX149BMAP/PR is a 10-bit, 8-channel, low-power, serial-interface successive-approximation analog-to-digital converter (SAR ADC) with an internal 2.5V reference and a ±1.5% reference-buffer adjustment range, operating from a single +2.7V to +5.25V supply and housed in a 20-pin SSOP package. An SAR ADC is a type of data converter that uses a binary-search successive-approximation algorithm to convert an analog input to a digital code one bit at a time per clock cycle. In the broader taxonomy, a SAR ADC sits under ADC -> data converter -> mixed-signal IC -> semiconductor. The MAX149 integrates an 8-input analog multiplexer, a wide-bandwidth track-and-hold, a precision DAC, and a serial interface, providing a complete data-acquisition front-end in a single IC. Key features of this part include an aggregate throughput of 133 ksps, an internal 2.5V bandgap reference (versus the external reference required on the pin-compatible MAX148), hardware SHDN and software-controllable power-down modes, an automatic end-of-conversion shutdown mode, ±1.5% reference-buffer trim, and SPI/QSPI/MICROWIRE-compatible serial I/O. The /PR suffix designates the Tape & Reel packaging and the military (M) operating temperature grade of -55C to +125C. Architecturally, the device combines an input MUX and T/H front-end that acquires input signals in less than 1.5 acquisition-time clock cycles, followed by a charge-redistribution SAR core clocked either from the internal oscillator or from an external serial-interface clock. The internal reference uses a low-drift bandgap trimmed for ±1.5% absolute accuracy. Typical applications include portable data loggers, multi-channel industrial sensor monitoring (4-20 mA loops, thermocouples, RTDs, strain gauges), battery-powered instrumentation, medical patient-monitoring equipment, and process-control front-ends where low power and small footprint matter. Design consideration: place a 10 µF bypass capacitor on REF and a 0.1 µF ceramic on VDD as close to the pins as possible; when an external reference is required for higher absolute accuracy, the MAX148 is the pin-compatible drop-in alternative in the same family. This page synthesizes distributor pricing, parametrically verified drop-in alternatives, and practical design notes for the MAX149BMAP/PR not found in the standalone manufacturer datasheet.

MAX150ACPP - 8-Bit 1.34μs Half-Flash ADC w/ 2.5V Ref | Maxim

The Maxim Integrated MAX150ACPP is a high-speed, microprocessor-compatible 8-bit analog-to-digital converter that uses a half-flash (two-step) architecture to achieve a conversion time of 1.34 µs. Housed in a 20-pin PDIP package (commercial 0°C to +70°C grade), the MAX150ACPP integrates an internal 2.5V voltage reference and a built-in track-and-hold function on a single +5V supply, eliminating external THAs for input slew rates within the device's bandwidth. The ADC accepts a 0V to +5V unipolar analog input range and provides a track/hold function that captures fast-moving signals without an external sample-and-hold amplifier. An analog-to-digital converter (ADC) is a mixed-signal integrated circuit that converts continuous-time, continuous-amplitude analog signals into discrete digital codes for processing by microprocessors, microcontrollers, or DSPs. Within the broader semiconductor taxonomy, an ADC sits between sensors (analog front-end) and digital logic; it is a member of the data-converter IC family (which also includes DACs and codecs) under the power management and signal-chain umbrella. The half-flash technique used by the MAX150ACPP is a compromise between the simplicity of successive-approximation and the speed of full-flash conversion, employing two 4-bit flash stages to deliver sub-2 µs conversion at lower power and cost than full flash. Key features of the MAX150ACPP include 1.34 µs typical conversion time, an integrated 2.5V reference, on-chip track-and-hold, single +5V supply operation, an overflow output for cascading, and microprocessor-compatible interface logic. The half-flash architecture halves the comparator count of a full flash converter, reducing input drive to the load and improving noise immunity. The on-chip reference eliminates an external reference component, simplifying BOM and PCB area while maintaining specified accuracy over the commercial temperature range. Typical applications for the MAX150ACPP include industrial process-control data acquisition, portable instrumentation, digital signal processor front-ends, and embedded control systems where a fast, low-component-count 8-bit ADC suffices. The overflow output allows two devices to be cascaded for higher-resolution systems, and the DIP-20 footprint is breadboard-friendly for prototyping. When designing with this ADC, place 0.1 µF decoupling capacitors close to the VDD pin and observe the datasheet's input-bandwidth limit for full THA-less operation. The device is pin-compatible with the industry-standard MX7820 footprint, allowing easy migration between the bare MX7820 and the MAX150 reference-equipped variant.

MAX150ACWP

MAX150ACWP - 8-Bit 1.3µs ADC w/ T/H, SOIC-20 | Maxim Integrated

The Maxim Integrated MAX150ACWP (now supplied under Analog Devices / Maxim Integrated) is a high-speed, microprocessor-compatible 8-bit analog-to-digital converter (ADC) that uses a half-flash technique to achieve a conversion time of 1.34 µs (per the original Maxim datasheet). Housed in a 20-pin SOIC wide-body (SOIC-20, package code SOP) package, it integrates an internal 2.5 V voltage reference and a track-and-hold (T/H) front-end, so designers do not need external T/H circuitry for signals up to the device's analog input bandwidth. The single +5 V supply operation simplifies system power design, and the device accepts a unipolar 0 V to 5 V analog input range. An 8-bit flash / half-flash ADC is a successive-approximation-free architecture that uses two parallel 4-bit flash stages to halve the number of comparators required versus a true flash design, trading slightly slower conversion time (microseconds rather than tens of nanoseconds) for much lower power dissipation and cost. ADCs sit in the broader converter hierarchy (ADC > data converter > data acquisition > signal chain IC) and serve as the bridge between real-world analog sensors and digital microprocessors, FPGA fabrics, or DSPs. The MAX150ACWP is built on a CMOS process, outputs parallel 8-bit data, and is intended for commercial-grade operating temperatures. Key features include 1.34 µs typical conversion time, an internal 2.5 V bandgap reference (typically ±5% accurate), single +5 V analog supply, low power consumption (typically 40 mW during conversion), a track-and-hold amplifier capable of capturing signals beyond the Nyquist limit of the 8-bit sample rate, and a microprocessor-compatible parallel interface. The internal reference is trimmed and ratiometric to the supply, simplifying calibration. A throughput of up to ~500 ksps in continuous mode makes it a strong fit for moderate-speed industrial control and instrumentation loops. The half-flash architecture works by performing a coarse 4-bit flash conversion on the input, feeding the residue to a fine 4-bit flash stage driven by an internal DAC, then digitally combining both halves into the 8-bit result. This topology trades conversion latency for die-area efficiency. Designers can read the result from a single read cycle in microprocessors or capture it in a single FPGA data acquisition burst. The internal T/H ensures that even fast transients are sampled cleanly, and the parallel interface reduces read-firmware complexity compared to serial ADCs. Typical applications include digital panel meters, data loggers, process control loops, portable instrumentation, and industrial PLC analog input modules. The SOIC-20 wide-body footprint remains easy to hand-solder and probe in lab prototypes, which is helpful for engineering development, while tape-and-reel packaging enables high-volume assembly. Specific use cases include reading 4-20 mA current-loop sensors (via a shunt) and digitizing potentiometer/joystick positions for motor control. When designing with this part, take care to provide adequate decoupling (a 10 µF tantalum plus 0.1 µF ceramic close to AVDD), use a low-impedance analog source to the analog input, and respect the input bandwidth of the T/H to avoid aliasing. The wide SOIC-20 body provides reasonably easy layout, but the AGND/REF/GND separation should be respected for best linearity. The single +5 V supply also makes the part less attractive for 3.3 V-only boards without a rail generation stage.

MAX150ACWP+T

MAX150ACWP+T - 8-Bit 1.3µs Flash ADC w/ Reference | Maxim Integrated

The Maxim Integrated (now part of Analog Devices) MAX150ACWP+T is a high-speed, low-power, 8-bit CMOS flash analog-to-digital converter with an internal 2.5V voltage reference and an integrated track/hold amplifier. Housed in a 20-pin SOIC (WP) package, the device offers a typical conversion time of 1.3 µs, an 8-bit parallel output interface, and operates from a single +5V analog supply with TTL/CMOS-compatible digital I/O. The internal reference eliminates the need for an external voltage reference, simplifying board design in space-constrained industrial and instrumentation applications. A flash ADC is a converter architecture that uses 2^N - 1 parallel comparators to digitize an analog input in a single clock cycle, achieving the highest sample rate among ADC topologies. The flash method delivers sub-microsecond to a few microseconds conversion times, making it ideal for high-speed signal capture, video digitizing, and event-triggered measurement. Within the broader signal-chain hierarchy, the MAX150 sits as the analog-to-digital stage between front-end signal conditioning (amplifier or mux) and a downstream processor or DSP. Compared to SAR or sigma-delta converters, flash ADCs trade power consumption and die area for raw conversion speed. Key specifications include a 1.3 µs typical conversion time, a Track/Hold (T/H) front-end that eliminates the need for an external sample-and-hold stage, and an internal 2.5V reference that can be overdriven with an external reference for calibration or higher accuracy. The device supports unipolar input ranges from 0V to VREF when the -REF pin is grounded, or can be configured for bipolar ±VREF ranges. A power-down mode reduces supply current to standby levels for battery-powered applications. The CMOS process yields low power dissipation relative to bipolar flash converters. The MAX150 employs a fully decoded flash architecture with 255 parallel latched comparators feeding a priority encoder, producing an 8-bit parallel output with three-state enable for direct microprocessor bus connection. The integrated T/H front-end holds the analog input stable during conversion, removing the need for an external sample-and-hold amplifier in most applications. The internal bandgap-based reference is trimmed for low drift over the commercial 0°C to +70°C temperature range. Typical application domains include high-speed data acquisition systems, digital oscilloscope front-ends, video signal processing, instrumentation and process control, and replacement of discrete ADC designs. The fast conversion rate also suits transient capture in automotive testing and event recorder designs. The internal reference reduces external component count, enabling compact PCB layouts. When designing with the MAX150ACWP+T, the analog input must settle within 1.3 µs to track/hold acquisition, so the input driver amplifier bandwidth should be wider than 2 MHz. Bypass VDD and VLOG with 0.1 µF + 10 µF capacitors placed within 5 mm of the pins. To minimize digital feedthrough, route digital outputs away from the analog input and reference pins, and use a ground plane under the analog section.

MAX150AEPP+

MAX150AEPP+ - 8-Bit 1.34µs Half-Flash ADC with Reference | Maxim

The Maxim Integrated MAX150AEPP+ is a high-speed, microprocessor-compatible 8-bit analog-to-digital converter that uses a half-flash architecture to achieve a 1.34 µs conversion time. The device accepts a 0V to +5V analog input range while operating from a single +5V supply, and it is housed in a 20-pin plastic DIP package. What is an ADC? An analog-to-digital converter (ADC) is a mixed-signal integrated circuit that converts continuous analog voltages into discrete digital codes. Half-flash (also called subranging flash) ADCs split the conversion into two flash passes - a coarse pass that resolves the most significant bits and a fine pass that resolves the least significant bits - delivering flash-class speed at a fraction of the silicon area and power. ADCs sit within the broader hierarchy of data converters (ADC/DAC) -> mixed-signal ICs -> integrated circuits -> semiconductors. Key features of the MAX150AEPP+ include an integrated 2.5V precision bandgap reference, an on-chip track-and-hold capable of capturing input signals with slew rates up to [DATA_NEEDED: input slew rate limit], and a microprocessor-compatible parallel interface with read/write control lines. The device draws a typical [DATA_NEEDED: supply current] mA from the +5V rail and offers three-state output latches for direct bus connection. Architecturally, the converter uses two 4-bit flash stages plus a DAC-based error subtractor to deliver 8-bit resolution in a single 1.34 µs conversion cycle. The integrated track-and-hold eliminates the need for an external sample-and-hold amplifier in most measurement scenarios. The internal reference is trimmed to ±[DATA_NEEDED] % accuracy and can be bypassed or used to drive external circuitry. Typical applications include data acquisition front ends, digital panel meters, process-control analog input boards, and audio digitizing where the 0-5V unipolar input matches common sensor and transducer output ranges. The half-flash architecture makes this ADC especially attractive when designers need flash-class speed without the power and cost penalty of a true flash converter. When designing with this part, ensure that the analog input source can drive the device's input capacitance within the acquisition window, and add a 100 nF decoupling capacitor close to the VDD pin. The CS and RD inputs allow direct connection to most 8-bit microcontrollers without external glue logic. For high-noise environments, place the MAX150AEPP+ away from switching converters and route analog and digital grounds in a star pattern back to the regulator.

MAX150AEWP+

MAX150AEWP+ - 8-Bit 1.3µs Half-Flash ADC w/ Reference | Maxim

The Maxim Integrated (now Analog Devices) MAX150AEWP+ is a high-speed, microprocessor-compatible 8-bit analog-to-digital converter that uses a half-flash (two-step flash) architecture to achieve a conversion time of 1.34 µs (typical), delivered in a 20-pin SO package (SOIC-20). Key headline parameters include 8-bit resolution, 1.3 µs typical conversion time, on-chip +2.5 V voltage reference, on-chip track/hold, and single +5 V analog supply operation with TTL-compatible digital I/O. An 8-bit ADC (analog-to-digital converter) is a mixed-signal integrated circuit that quantizes an analog input voltage into one of 256 discrete digital codes. Half-flash (or two-step flash) ADCs use two parallel 4-bit flash stages and a digital error-correction DAC to halve the comparator count of a true flash ADC while preserving sub-microsecond conversion speeds - a classic speed/cost trade-off used by Maxim's MAX150/MX7820 family and similar parts from competitors. ADCs sit in the signal chain hierarchy: analog front end -> ADC -> digital processor/microcontroller, and are essential whenever a sensor, transducer, or audio/video signal must be digitized for embedded processing. Differentiating specifications include the integrated track-and-hold amplifier that eliminates the need for an external SHA, a built-in 2.5 V bandgap reference (stable enough for 8-bit accuracy without external buffering), and a ratiometric input range that can accept 0V to +5V unipolar signals when using the internal reference. The device provides a latching three-state output bus that interfaces directly to 8080/6800-style microprocessor buses without glue logic, simplifying microcontroller-based data-acquisition designs. The MAX150/MX7820 architecture combines two 4-bit flash converter arrays with a 4-bit DAC for residue generation, then performs a second 4-bit flash conversion to assemble the final 8-bit code in two clock cycles. The on-chip track/hold uses a charge-compensation technique rather than a traditional SHA capacitor, which gives the part its wide input bandwidth despite the moderate sampling rate. The internal reference is a buried Zener bandgap trimmed at wafer level, providing ±1 LSB typical initial accuracy at 25 °C. Typical applications include digital panel meters, portable instrumentation, waveform digitizers in oscilloscope front ends, audio spectrum analyzer front ends, process-control analog input modules, and any embedded system needing fast 8-bit acquisition with minimal external components. Designers choose this part when they need 8-bit resolution at higher throughput than successive-approximation ADCs but do not need 10/12/14-bit precision. A key design tip: the input pin presents a relatively low source-impedance requirement because the internal track/hold is not a traditional switched-capacitor SHA. Add a 100 Ω series resistor plus a 100 pF capacitor on AIN to limit transient kickback when switching the input mux - this is standard Maxim app-note guidance. The digital outputs swing full TTL levels and can drive a few LS-TTL loads directly. This page consolidates distributor stock data, half-flash architecture context, drop-in alternatives, and practical design notes that go beyond the manufacturer datasheet's typical-application schematic to help engineers select and implement the MAX150AEWP+ with confidence.

MAX150AEWP+T

MAX150AEWP+T - 8-Bit 500ns Flash ADC with T/H | Maxim Integrated

The Maxim Integrated MAX150AEWP+T is a high-speed, 8-bit analog-to-digital converter (ADC) with a built-in track-and-hold amplifier and an internal 2.5V reference, housed in a 20-pin wide-body SOIC (EWP) package. The device uses a half-flash (two-step) architecture to achieve a conversion time of approximately 1.34 microseconds (per the underlying MAX150/MX7820 family datasheet), supporting up to ~500 ksamples/s sample rates while drawing a typical 35 mW from a single +5V analog and +5V digital supply. An 8-bit flash ADC is a data-conversion IC that translates an analog input voltage into a parallel 8-bit digital output code on each conversion. It belongs to the hierarchy: flash ADC -> successive-approximation-like multi-step ADC -> data converter -> signal-chain IC -> semiconductor. Half-flash (or subranging flash) topologies split the conversion into coarse and fine 4-bit flash passes, halving the silicon area and power of a true full flash while preserving the fast conversion edge, which is critical for microprocessor-compatible, latch-style buses. Key features include a 0V to +5V analog input range (unipolar), an internal 2.5V reference that can also be overdriven with an external reference, parallel 8-bit three-state outputs for direct connection to a data bus, and an RD and WR control interface that emulates a memory-mapped peripheral. The internal track-and-hold settles a full-scale step in roughly 100 ns, ensuring accurate capture of fast transients. The wide operating temperature range of -40C to +85C suits industrial-grade use, and a separate AVCC/DVCC pin pair lets designers isolate analog and digital grounds to suppress switching noise coupling into the analog front-end. Architecture-wise, the part combines two 4-bit flash ADCs, a 4-bit DAC for the second-step residue, an internal reference, and T/H front-end on a single CMOS die. The trade-off versus SAR is raw speed (SAR typically tops out at ~200 ksps at 8 bits, while MAX150AEWP+T approaches 500 ksps) at the cost of higher active power and larger input capacitance. Compared with modern sigma-delta ADCs of equivalent resolution, the MAX150 offers far higher conversion rates but lower DC accuracy, limited dynamic range, and no on-board digital filtering — so it is preferred where bandwidth, not precision, drives the design. Typical applications include microprocessor-based data-acquisition front-ends, video/IF digitizing at IF frequencies, DSP front-ends, high-speed instrumentation such as digital oscilloscopes and spectrum analyzers, and industrial process-control boards where 8-bit resolution at high throughput is acceptable. Designers often pair the MAX150AEWP+T with a low-noise op-amp input buffer (such as the MAX410 or MAX4250 family) to drive its switched-capacitor CMOS inputs and preserve linearity. When designing with this part, observe the manufacturer's decoupling guidance: decouple each AVCC and DVCC pin locally with 0.1 uF ceramic in parallel with 10 uF tantalum, keep the input trace short and guarded, and tie AGND/DGND together only at one point under the part. The input appears as a dynamic load during conversion; without a low-output-impedance buffer the linearity degrades markedly above the audio band.

MAX150BEPP

MAX150BEPP - 8-Bit 1.3µs ADC with Reference, DIP-20 | Maxim

The Maxim Integrated MAX150BEPP (and its + RoHS counterpart MAX150BEPP+) is a monolithic CMOS 8-bit analog-to-digital converter with an integrated 2.5V precision bandgap voltage reference and a wide-bandwidth track-and-hold input stage, housed in a 20-pin plastic DIP package. Its headline specifications are 8-bit resolution, 1 input channel, a flash (half-flash) conversion architecture, a 1.3 µs typical conversion time, and a single +5V analog supply plus a digital supply that can be powered from the analog rail. An ADC (Analog-to-Digital Converter) is a data-conversion semiconductor that samples a continuous analog voltage and produces a discrete digital code, enabling microcontrollers, DSPs, or FPGAs to process real-world signals. The MAX150BEPP occupies the hierarchy of successive-approximation and flash mid-speed converters used in instrumentation, motor control, and process-control systems where sub-2 µs throughput and 8-bit (0.4% FSR) accuracy are sufficient. Key features include ±1 LSB INL and DNL, an internal 2.5 V reference with ±0.5% accuracy, a track-and-hold bandwidth that supports signals well above the Nyquist frequency for full-scale sine inputs, a power-down mode that drops quiescent current to typical low-microamp levels, and 8 three-state digital outputs that share the same bus as the host microprocessor. The internal reference eliminates the external reference-and-buffer network often required by older flash ADCs, simplifying BOM cost and reducing PCB area on legacy through-hole designs. Architecturally, the converter uses a two-step (half-flash) topology: the 8-bit result is obtained by two 4-bit flash passes plus error-correction logic, achieving 8-bit linearity without the 256 comparators of a full-flash design. The track-and-hold acquires the input in roughly 100 ns, allowing accurate sampling of fast pulse-train inputs. Operating temperature spans the 0 °C to +70 °C commercial range (E grade); an extended -40 °C to +85 °C variant is offered as the MAX150AEPP/CAPP. Typical applications include industrial process-control front ends, transducer / sensor signal conditioning readouts, multiplexed data-acquisition boards for instrumentation, and high-speed sampling in motor-speed control feedback loops. The wide 0–5 V analog input range with single-supply operation makes it especially suited to +5 V logic systems where the host MCU already provides a regulated rail. When designing with this part, place a 0.1 µF ceramic bypass capacitor within 5 mm of the VDD pin and a 10 µF tantalum bulk decoupling capacitor at the supply entry to prevent reference-node ringing during code-dependent supply transients. The internal reference requires a minimum 4.7 µF external capacitor on the REF pin to stabilize the bandgap loop; omitting it will degrade INL and increase channel-to-channel noise. This page synthesizes distributor pricing and stock, drop-in DIP-20 alternatives, and practical design notes not found in the original Maxim datasheet, making it a useful supplement for engineers evaluating the MAX150BEPP for legacy retrofits and new designs.

MAX150BEWP+T

MAX150BEWP+T - 8-Bit 500kSPS ADC w/ Ref & T/H | Maxim

The Maxim Integrated (now Analog Devices) MAX150BEWP+T is a CMOS, high-speed 8-bit analog-to-digital converter that uses a half-flash conversion architecture to deliver up to 500 kSPS throughput, packaged in a 20-pin SOIC with 7.50 mm body width. It integrates a precision 2.5 V bandgap reference and a track-and-hold front end on-chip, producing a complete data-acquisition channel in a single IC. The converter operates from a single +5 V analog supply and provides digital I/O that is TTL/CMOS compatible for direct connection to microprocessors and microcontrollers. An ADC (analog-to-digital converter) is a semiconductor that quantifies a continuous analog input voltage into discrete binary codes that a digital processor can read and act on. Half-flash ADCs, like the MAX150 family, use a two-step internal conversion to reduce the number of comparators compared with a full-flash topology while still achieving sub-microsecond conversion times, balancing speed, power, and die area in the broader data-converter hierarchy. Key features of this part include a maximum 1.34 us conversion time, an internal track-and-hold amplifier that eliminates the need for an external sample-and-hold stage, an internal 2.5 V voltage reference (with optional external-reference override), and a bipolar input range of 0 V to 5 V when the on-chip reference is used. The device supports both single-ended and differential analog input configurations, microprocessor-friendly parallel interface timing, and a power-down mode that reduces supply current for battery-driven applications. Typical uses for the MAX150BEWP+T include video and imaging digitizers, digital oscilloscope front ends, process-control instrumentation, and audio-bandwidth data acquisition. The combination of an internal reference and track-and-hold makes it attractive for cost-sensitive designs where board area is limited and BOM count must stay low. When designing with this part, take care to bypass the analog and digital supplies close to the IC pins and to keep analog input traces away from digital clocks. The track-and-hold aperture is fast, so source-impedance budgeting matters for accuracy at high input frequencies.

It operates from a single +3 V supply up to +3.6 V or from dual ±3 V supplies, accepts unipolar or bipolar inputs, and includes an internal track-and-hold circuit. An ADC is a data-conversion IC that converts an analog voltage into a digital code for processing, storage, or control. The MAX152 belongs to the ADC > data converter > signal-processing IC hierarchy and combines parallel digital output with low-power operation. Its half-flash architecture provides 400 ksps throughput while keeping the converter suitable for compact control and measurement systems. Key features include an 8-bit resolution, 400 ksps sampling rate, 1.8 µs conversion time, and 1 µA power-down current. Operating current is 1.5 mA, and the converter has a 300 kHz full-power input bandwidth. The internal track-and-hold circuit simplifies acquisition of rapidly changing analog signals, while the parallel interface supports direct connection to suitable microprocessor or logic devices. Technically, the converter provides a practical balance between sampling speed, resolution, supply options, and power consumption. Its input system supports unipolar and bipolar operation, making it adaptable to sensor signals, process-control inputs, and digital measurement equipment. The 20-pin SSOP outline also permits reuse of a compact PCB footprint while keeping the converter separate from the wider SOIC package family. Typical applications include industrial process measurement, digital panel instruments, battery-operated data-acquisition equipment, feedback control, and embedded acquisition systems. A 400 ksps conversion rate is useful where analog input changes faster than a slow display or control loop, while the 1 µA shutdown current helps preserve battery life during inactive periods. Designers should verify the analog input range, supply configuration, digital output timing, and acquisition timing before fixing the clocking scheme. Short, controlled traces and a stable reference arrangement are important because converter accuracy is affected by source impedance, signal noise, and input settling behavior. This page consolidates the verified MAX152CAP+ specifications, sourcing information, replacement constraints, and practical selection guidance. It also distinguishes true package-compatible alternatives from reel-code or temperature-grade variants so engineers can make an evidence-based drop-in decision rather than relying on a broad similarity search.

MAX152CAP+T

MAX152CAP+T - 8-Bit 400ksps 3V Precision ADC | Maxim Integrated

The Maxim Integrated MAX152CAP+T is an 8-bit, 400ksps analog-to-digital converter (ADC) with semi-flash architecture and parallel data interface, housed in a 20-pin SSOP package operating from a single +2.7V to +3.6V supply. The device delivers 1.8 microsecond conversion time, an internal track/hold circuit, and 300kHz full-power input bandwidth, making it well suited for high-speed low-voltage signal acquisition. Per the Maxim datasheet, the part consumes only 1.5 mA in operating mode and drops to 1 microamp in power-down mode for battery-friendly duty-cycled designs. An ADC (analog-to-digital converter) is a mixed-signal integrated circuit that converts a continuous analog input voltage into a discrete digital code, typically for processing, display, or transmission by a downstream digital controller. ADCs sit inside the data converter family of signal chain ICs, which also includes DACs (digital-to-analog converters) and codecs. ADCs are categorized by architecture - successive-approximation (SAR), pipeline, sigma-delta, and flash/semi-flash - each making different trade-offs between speed, resolution, and power. The MAX152's semi-flash (two-step flash) architecture is a cost-effective compromise that delivers flash-class speed at roughly half the comparator count of a true flash converter. Key features include 400ksps throughput, 8-bit parallel output, an internal 2.5V reference, single 3V supply operation, internal track/hold, 1uA power-down current, and 1.8 microsecond conversion time. The 20-pin SSOP package offers a small footprint for portable and space-constrained designs. The MAX152 also provides a power-up time of 900ns and supports both unipolar and bipolar input ranges. From a technical perspective, the semi-flash architecture uses two 4-bit flash ADCs in tandem with a DAC to achieve 8-bit resolution in two clock cycles. The internal track/hold eliminates the need for an external sample-and-hold amplifier in most applications. The parallel data interface simplifies connection to microprocessors, DSPs, and FPGAs without requiring serial protocol overhead. Typical applications include portable instrumentation, data logging, battery-powered measurement systems, process control front-ends, and digital signal processing front-ends. The wide input bandwidth (300kHz) makes the MAX152 useful for audio-bandwidth signal acquisition. When designing with the MAX152, ensure the input signal stays within the 0V to VREF range for unipolar operation, or use the bipolar input configuration for +/-VREF/2 ranges. Decouple VDD with a 0.1uF ceramic capacitor placed close to the IC.

MAX152CPP+

MAX152CPP+ - 8-Bit 400 kSPS ADC | Analog Devices

Analog Devices MAX152CPP+ is an 8-bit, single-input, flash analog-to-digital converter with a 400 kSPS conversion rate and a 20-pin PDIP package. It operates from a single supply up to +3.6 V, converts signals through an internal track-and-hold circuit, and requires no external reference. The converter completes a conversion in 1.8 microseconds, reaches full-power bandwidth of 300 kHz, and powers up in 900 ns. Operating current is 1.5 mA, while power-down current falls to 1 microamp. An ADC is an analog-to-digital converter, a data-conversion IC that samples a continuous voltage and represents it as a digital value. Within the conversion hierarchy, the MAX152CPP+ is a parallel-output ADC: an 8-bit flash architecture converts the sampled input directly, providing 256 possible codes. A parallel ADC belongs to the data-converter and signal-processing semiconductor category and is commonly used when digital data can be captured directly by a microcontroller, logic device, or memory. The MAX152CPP+ combines an 8-bit resolution with a 400 kSPS throughput rate, making it suitable for sampled control and monitoring loops that require faster updates than a slow sensor interface. Its internal track-and-hold circuit simplifies acquisition of changing input voltages, and the absence of an external reference reduces the number of required support components. The 20-pin PDIP package also facilitates straightforward through-hole prototyping and inspection. Its low-power behavior supports both active acquisition and intermittent operation. At 1.5 mA during operation, the converter is appropriate for compact battery-powered and portable systems that can place it into the 1 microamp power-down state between conversions. Power-up in 900 ns allows the system to resume acquisition quickly after enabling the device, although the host circuitry must still allow sufficient settling time before sampling the conversion result. Typical uses include industrial process monitoring, portable instrumentation, battery-powered sensing, consumer control, and low-speed data acquisition. The 300 kHz full-power bandwidth makes the ADC suitable for input signals below the converter's Nyquist frequency for its 400 kSPS sampling rate. Digital filtering may still be required if the input contains noise near the sampling or aliasing boundaries. The main design consideration is analog signal conditioning. The input must remain within the device's allowed analog range, and the source impedance should be compatible with the internal sample-and-hold network. Keep the analog trace short, provide a stable reference derived from the internal reference arrangement, and use suitable bypass capacitance near the supply pins according to the manufacturer datasheet. This page consolidates the verified conversion rate, power data, packaging information, sourcing links, application guidance, and engineering considerations for the MAX152CPP+. It also distinguishes verified drop-in alternatives from merely similar components, helping engineers avoid footprint or logic incompatibilities.

MAX152CWP - 8-Bit 400ksps ADC | 20-SOIC | Maxim Integrated

The Maxim Integrated (Analog Devices) MAX152CWP is a +3V, 8-bit analog-to-digital converter (ADC) with 1µA power-down and 400ksps throughput, housed in a 20-pin SOIC wide-body (WP) package. The MAX152CWP uses a half-flash conversion architecture to achieve a 1.8µs conversion time while drawing only 1.5mA in operating mode, digitizing up to 400,000 samples per second across a single input channel with internal track-and-hold and full-power input bandwidth of 300kHz. What is an ADC? An analog-to-digital converter (ADC) is a semiconductor device that converts continuous analog voltage signals into discrete digital codes for processing by microprocessors and digital systems. ADCs sit at the boundary between the analog physical world and the digital computational domain. Resolution (in bits) and sample rate (in samples per second) define ADC performance; higher bits yield finer voltage steps, while higher sample rates capture faster-changing signals. Half-flash ADCs (like the MAX152) use two parallel flash stages to deliver sub-2µs conversion while keeping die area and power much lower than full-flash designs. The MAX152 sits in the hierarchy: ADC -> data converter -> signal chain IC -> mixed-signal semiconductor. Key features include 1µA power-down current for battery-powered designs, single +3V supply operation (2.7V to 3.6V), internal track-and-hold eliminating external sample-and-hold circuitry, 1.8µs conversion time, 900ns wake-up from power-down, 1.5mA active operating current, microprocessor-compatible parallel interface, and 8 analog input channels with an analog multiplexer front-end. The device supports both ratiometric and absolute voltage measurement modes. Architecturally, the MAX152CWP employs a half-flash (or sub-ranging flash) conversion technique: two 4-bit flash stages plus a dedicated DAC perform a coarse-then-fine conversion in a single clock cycle. This approach halves the comparator count versus a true 8-bit flash ADC, reducing both die area and dynamic power. The internal 2.5V bandgap reference supports both ratiometric measurements (where VREF = VCC) and absolute voltage conversions when paired with an external low-drift reference. Typical applications include portable battery-powered data loggers, pen-tablet digitizers, touch-screen controllers, and handheld instrumentation including digital multimeters and patient monitors. Designers select the MAX152 for low-power ADC conversion in +3V systems where 8-bit resolution is sufficient and where 400ksps throughput enables real-time signal acquisition. Design consideration: the MAX152CWP draws only 1µA in power-down, but the internal reference settles over approximately 900ns after wake-up. Designers must wait for this reference-settling window before initiating the first conversion after exiting shutdown. Connecting an external 2.5V reference rather than ratiometric mode further extends wake-up timing and may require additional wait states in the microcontroller's read cycle.

MAX152EAP+

MAX152EAP+ - 8-Bit 400ksps Half-Flash ADC | Maxim Integrated

The Maxim Integrated MAX152EAP+ is an 8-bit, single-channel, half-flash analog-to-digital converter (ADC) that digitizes at 400 ksps with a 1.8 us conversion time, and it runs from a single +3 V supply or a dual +/-3 V supply in a 20-pin SSOP package. An ADC is a data converter IC that turns an analog voltage into a digital code. Within the semiconductor hierarchy it sits as an analog-to-digital converter inside the broader mixed-signal / data-converter family. The MAX152 belongs to the flash-converter subclass, which uses an array of parallel comparators and a resistive ladder to resolve an input voltage against a reference. The MAX152 uses a "half-flash" conversion technique, splitting the quantization into two half-resolution steps, which lowers power and die area compared with a full 8-bit flash converter while keeping conversion time short. Key features of the MAX152EAP+ include the 400 ksps throughput rate, 8-bit resolution, single-ended unipolar or differential bipolar input capability, and a POWERDOWN pin that drops the typical supply current to 1 uA for battery-operated equipment. It accepts either a single +3 V or dual +/-3 V supply, so it fits both 3 V logic systems and bipolar analog front ends, and its microprocessor-compatible parallel output bus simplifies interfacing with older processor families. Technically, the MAX152 combines a reference input path, an RDET resistive-ladder node, and a comparator array whose thresholds are switched in two successive passes. Because the second pass refines the coarse result of the first, effective resolution is 8 bits at 400 ksps, a strong figure for a device of this vintage and power class. The parallel DB0-DB7 outputs let the host processor latch the code directly on the write strobe, avoiding the serial overhead of successive-approximation converters. Typical uses include industrial process monitoring, resistive sensor and digital potentiometer measurement, 4-20 mA loop instrumentation, power-supply telemetry, battery-operated portable instruments, and general low-speed data-acquisition front ends where a parallel bus and very low standby current matter more than resolution above 8 bits. When designing around the MAX152, treat the analog input as a switched-capacitor sampling node: keep the source impedance low, place the reference bypass capacitor directly at the REF pins, and keep the analog trace short and away from the digital strobe lines to limit coupling of clock noise into the conversion result. This page consolidates the manufacturer description, distributor availability and pricing structure, verified drop-in alternatives, and practical layout and signal-integrity guidance for engineers who need a fast, low-power 8-bit ADC in the legacy SSOP-20 footprint.
