MAX1480EACPI+

MAX1480EACPI+ - 2.5Mbps Isolated RS-485/422 | ADI

The Analog Devices MAX1480EACPI+ is an isolated, half-duplex RS-485/RS-422 transceiver with one driver and one receiver, a 2.5 Mbps maximum data rate, and a 28-pin PDIP package. It operates from a 4.5 V to 5.5 V supply and provides 15 kV ESD protection on the communications interfaces. An isolated RS-485/RS-422 transceiver is a data-interface circuit that transfers digital signals between systems while providing electrical isolation between the host logic and the cable-side network. The MAX1480EACPI+ combines a differential line driver, differential receiver, isolation barrier, fail-safe receiver circuitry, and low-power standby capability. This places it within the transceiver hierarchy of interface ICs, communication ICs, and industrial data-conversion components. The principal benefits are its 2.5 Mbps operating speed, 15 kV ESD protection, isolated outputs, and support for both RS-485 and RS-422 networks. The device is particularly useful where a controller must connect to a long or electrically noisy cable without exposing the local electronics directly to the bus environment. Its integrated isolation also helps suppress ground-potential and common-mode disturbances between connected equipment. MAX1480EA-series devices use unrestricted driver slew rates for higher-speed communication, whereas MAX1480EC-series devices use reduced slew rates to minimize electromagnetic interference and cable reflections at lower data rates. The MAX1480EACPI+ is therefore most appropriate for links requiring the faster 2.5 Mbps capability rather than reduced-slew-rate operation. Its half-duplex arrangement supports a shared bus when only one transmitter is active at a time. Typical applications include automated test equipment, industrial-control networks, building-control systems, local area networks, telecom equipment, and isolated RS-485 or RS-422 data interfaces for EMI-sensitive installations. The 28-pin PDIP package favors legacy through-hole industrial equipment, test systems, and prototype platforms that have been designed around a conventional DIP footprint. For a new PCB, verify the complete pin description and isolation requirements in the manufacturer datasheet before assigning external nodes. Use appropriate bus protection, cable termination, grounding, and isolation barriers at the system level; the integrated 15 kV ESD protection does not remove the need for a sound surge and cabling strategy. This page consolidates the verified electrical ratings, package information, temperature range, and application requirements while adding engineering guidance for bus layout, protection, and component selection. It also identifies a temperature-grade alternative and clearly distinguishes the limits of the available drop-in replacement set.

MAX1480EAEPI+

MAX1480EAEPI+ - Isolated RS-485/RS-422 Transceiver | Analog Devices

Analog Devices MAX1480EAEPI+ is an isolated RS-485/RS-422 data-interface transceiver with one driver and one receiver, a 4.5 V to 5.5 V supply range, and ±15 kV ESD protection. It is housed in a 28-pin plastic DIP package and is intended for isolated, noise-sensitive industrial communication links. An isolated RS-485/RS-422 transceiver is a semiconductor interface that combines differential line-driver and receiver functions with electrical isolation between the logic-side and bus-side circuits. In the hierarchy of electronic components, it is an interface transceiver, then a line driver and receiver, and finally a data-communication semiconductor. The MAX1480EAEPI+ supports both RS-485 and RS-422 networks while separating sensitive logic equipment from the communication cable. Key features include ±15 kV ESD protection on the I/O pins, single-side power isolation, a fail-safe receiver circuit, and low-power standby operation. The 4.5 V to 5.5 V operating supply supports conventional 5 V equipment, while the differential interface helps reject common-mode noise picked up by long cables. The listed operating temperature range is 0°C to +70°C. The MAX1480EAEPI+ is implemented as a complete isolated data interface rather than a simple line transceiver. Its hybrid construction provides both driver and receiver functions on one board, reducing the number of components needed for a bidirectional isolated link. Its 28-PDIP format supports through-hole assembly and straightforward prototype or repair work where a surface-mount isolator is unnecessary. Typical applications include industrial-control networks, building-control networks, automated test equipment, local-area networks, telecom transceivers, and other EMI-sensitive RS-485 or RS-422 links. The isolation barrier can help limit ground-potential and surge-related stress between a host controller and an externally connected bus. For a new design, confirm the transceiver voltage, temperature range, isolation requirements, bus loading, termination strategy, and ESD environment before assigning the DIP footprint. Keep bus-side and logic-side return paths separated according to the manufacturer datasheet, and place protective network components close to the connector when additional surge protection is required. This product page combines the manufacturer family information with distributor specifications, package details, drop-in-family comparisons, and practical interface-design guidance. It helps engineers identify whether the MAX1480EAEPI+ matches a legacy 28-pin isolated RS-485/RS-422 design and where additional qualification is required before substitution.

MAX1480ECCPI+

MAX1480ECCPI+ - Isolated RS-485/RS-422 Transceiver | Analog Devices

Analog Devices MAX1480ECCPI+ is an isolated RS-485/RS-422 data-interface transceiver with one driver and one receiver, ±15 kV ESD protection, and a 4.5 V to 5.5 V supply range. The device is housed in a 28-pin PDIP package. It is designed for industrial communication links that benefit from galvanic isolation and robust protection against electrostatic discharge. An RS-485/RS-422 transceiver is an interface integrated circuit that combines differential line-driver and receiver functions for reliable, noise-resistant data transmission over balanced wiring. The MAX1480ECCPI+ belongs to the broader interface IC hierarchy, where it connects digital logic to industrial communication buses. Its isolated transmitter and receiver reduce conductive noise paths between a host system and an external RS-485 or RS-422 network, improving robustness where ground-potential differences or long cables are concerns. Key characteristics include ±15 kV ESD protection, 4.5 V to 5.5 V operation, one differential driver, one differential receiver, and operation with both RS-485 and RS-422 networks. The 28-pin PDIP package supports through-hole assembly and straightforward inspection or rework. The component is specifically listed for new designs by the manufacturer through the MAX1480E family page. The MAX1480ECCPI+ combines a data-interface transceiver with isolation in a single package. This simplifies board partitioning compared with a non-isolated transceiver plus separate isolation components. Isolation-related timing, creepage, capacitance, and transient-protection details should nevertheless be checked against the complete manufacturer datasheet before finalizing a high-speed or high-noise design. Typical applications include isolated industrial RS-485 links, factory automation equipment, building-control systems, instrumentation, data acquisition, and communications equipment. The differential interface is particularly useful when the bus must tolerate electrically noisy industrial environments while maintaining a clear separation between equipment-ground domains. Designers should preserve the recommended isolation barrier, provide adequate input and output bypassing, route the isolated bus through appropriately protected interfaces, and account for connector-level surge and ESD requirements. The ±15 kV device rating does not eliminate the need for correct system grounding, cable routing, and external protection. This product page consolidates the manufacturer family information, interface characteristics, drop-in family alternatives, and application-specific engineering guidance. It is intended to help designers evaluate the MAX1480ECCPI+ for isolated RS-485 and RS-422 communication systems without relying on isolated snippets from individual listings.

MAX1480ECEPI+

MAX1480ECEPI+ - Isolated RS-485/RS-422 Transceiver | Analog

Analog Devices MAX1480ECEPI+ is an isolated RS-485/RS-422 data-interface transceiver with one driver and four receivers, a 4.5 V to 5.5 V supply range, and a 28-pin PDIP package. The interface provides ±15 kV ESD protection for industrial data lines while galvanic isolation separates the bus side from the logic side. An RS-485/RS-422 transceiver is a physical-layer interface IC that converts digital logic signals into differential bus levels and receives differential bus signals. In the component hierarchy, it belongs to interface ICs and data transceivers, supporting the larger category of communication semiconductors. Its isolation function helps prevent ground-potential differences and common-mode transients from coupling between equipment and a remote bus. The MAX1480ECEPI+ combines one transmit driver with four receive channels in one 28-pin package. Its 4.5 V to 5.5 V operating supply supports conventional 5 V communication equipment. The ±15 kV ESD rating is the principal protection figure specified for exposed data-interface pins, making the device suitable for industrial environments where cables can acquire electrostatic discharge before reaching the equipment. This device is intended for isolated RS-485 and RS-422 links used to connect controllers, sensors, data-acquisition equipment, and remote instrumentation. The single-driver, four-receiver arrangement supports a point-to-multipoint topology when the bus wiring, termination, and grounding strategy are designed correctly. RS-422 favors point-to-point or one-driver configurations, while RS-485 permits multiple drivers under controlled bus management. A principal design consideration is that isolation does not replace correct bus engineering. The data lines still require suitable protection, cable routing, characteristic-impedance control, termination at appropriate endpoints, and common-mode analysis. The ±15 kV ESD capability should also be understood as an interface protection specification rather than a guarantee against every external surge event. Engineers should consult the manufacturer datasheet for the complete pin-description table, isolation ratings, timing, recommended application circuit, and package dimensions before assigning PCB tracks. DIP-28 construction also requires adequate spacing for through-hole assembly and should be checked against the enclosure, connector, and thermal requirements of the final system. This page combines the confirmed interface, supply, protection, package, and topology characteristics with application guidance, a parameter-level comparison, and actionable layout considerations. It is designed to help engineers identify the correct isolated transceiver while separating confirmed device facts from parameters that require review in the manufacturer documentation.

MAX14821ETG+

MAX14821ETG+ - IO-Link Device Transceiver, 24-TQFN | Analog Devices

The Analog Devices MAX14821ETG+ is an IO-Link device transceiver in a 24-pin TQFN (4x4 mm) package designed for industrial sensor and actuator networks operating on the 24V IO-Link standard. It supports all IO-Link data rates (COM1/COM2/COM3 at 4.8/38.4/230.4 kbps), operates from a 9V to 36V supply range, and integrates C/Q and DO drivers that are independently configurable for push-pull, high-side (PNP), or low-side (NPN) operation. The device detects the IO-Link C/Q wake-up condition and generates a wake-up signal on the active-low WU output for microcontroller power management. Two internal linear regulators (3.3V and 5V) generate common sensor and microcontroller supply rails from the 24V bus, reducing BOM count in industrial sensor heads. An IO-Link device transceiver is a physical-layer interface IC that bridges a microcontroller (running the data-link layer protocol) to the 24V IO-Link master port on the fieldbus. In the broader taxonomy, it belongs to sensor interface ICs, then industrial interface ICs, then interface ICs, and ultimately the integrated circuits family. IO-Link (IEC 61131-9) is a point-to-point, bidirectional digital communication standard that replaces traditional 4-20 mA and binary 24V signaling with a single standardized cable carrying both power and process data, enabling predictive maintenance and rich diagnostic data on factory floors. Key features of the MAX14821ETG+ include 1/1 transceiver topology, integrated surge protection for industrial 24V lines, selectable C/Q and DI current loads for actuator use, and a wide -40C to +85C industrial operating temperature range. The C/Q driver is rated for the high-current switching demanded by industrial actuators, while the DI (digital input) and DO (digital output) channels support legacy 24V binary sensor and actuator signaling. The integrated 5V/3.3V LDO outputs eliminate the need for external regulators in most sensor head designs, while the WU output pin enables ultra-low-power sleep modes for IO-Link-compliant wake-up sequences. From an architectural standpoint, the MAX14821ETG+ integrates the 24V physical layer, two LDO regulators, surge/transient protection, and configurable driver stages into a single die. This level of integration allows a complete IO-Link device node to be built with the MAX14821ETG+, a microcontroller, and minimal external passives. The device is designed to meet IEC 61131-9 IO-Link specifications and the IEC 61000-4-2 ESD and surge immunity requirements typical of industrial 24V environments. Typical applications include IO-Link smart sensors (photoelectric, inductive, capacitive, pressure), IO-Link valve manifolds and binary actuators, industrial 24V binary sensors with wake-up capability, and factory automation I/O modules. It is also well-suited for distributed I/O blocks, proximity switches, and condition-monitoring sensor heads where the 24V bus doubles as both power supply and communication line. When designing with this transceiver, ensure that the C/Q and DO driver configurations match the connected load (sink vs source) before commissioning, and place the bulk 24V decoupling capacitor close to the VSUP pin to ride through industrial surge events. Designers should also account for the thermal dissipation of the integrated LDOs when sourcing 100 mA continuously to the microcontroller rail. This page synthesizes distributor pricing, same-family drop-in alternatives, and practical design notes that go beyond what is reproduced in the manufacturer datasheet, helping engineers accelerate their IO-Link device development and source decisions.

MAX14850ASE+ - 6-Channel 600Vrms Digital Isolator | Analog Devices

The Analog Devices (formerly Maxim Integrated) MAX14850ASE+ is a six-channel digital isolator in a 16-pin SOIC (NSOIC) package that delivers up to 50 Mbps signaling and 600 Vrms isolation voltage across a monolithic silicon-dioxide barrier. It supports 3 V to 5.5 V power domains on both sides of the isolation barrier, a 1.5 kV/us minimum common-mode transient immunity (CMTI), and 30 ns typical propagation delay. A digital isolator is a semiconductor device that transfers logic signals across an isolation barrier using capacitive or magnetic coupling rather than opto-coupling or transformer coupling. Isolators sit in the system hierarchy between level shifters (which do not provide galvanic isolation) and reinforced safety isolators (which add redundant barriers for medical and high-voltage applications). The MAX14850 family uses Maxim's proprietary monolithic process technology to integrate the isolation barrier and transceivers onto a single die, reducing BOM cost versus traditional optocoupler or discrete transformer solutions. Key features include 600 Vrms working voltage rating, 2.5 kVrms surge capability per IEC 61000-4-5 referenced in the manufacturer datasheet, six independent unidirectional channels configured as 3 forward / 3 reverse, low power consumption of 2.5 mA per channel at 1 Mbps, 25 kV/us typical CMTI, and a wide operating temperature range of -40 C to +105 C. The device requires no external components other than standard bypass capacitors on each supply pin. The MAX14850 architecture combines on-chip transformers or capacitive couplers with Manchester-style or pulse-encoded data transmission to achieve robust common-mode rejection. Its monolithic integration eliminates the LED aging and CTR degradation that affect optocouplers, yielding stable performance over temperature and end-product lifetime. Typical applications include isolated RS-485/RS-232 transceivers, industrial fieldbus (Modbus, Profibus), isolated SPI and GPIO interfaces for microcontroller I/O expansion, medical patient-monitoring equipment requiring 1 x MOPP, solar inverter gate-drive signal isolation, and battery management systems in electric vehicles. When designing with this part, ensure each VDD pin is bypassed with a 0.1 uF ceramic capacitor placed within 2 mm of the IC body, and route high-speed signal traces on the inner PCB layers using a controlled-impedance stack-up to maintain signal integrity across the isolation barrier. Confirm that the board-level creepage and clearance distances for the 600 Vrms rating meet the application's pollution-degree and altitude derating requirements per IEC 60664-1.

MAX14851AEE+

MAX14851AEE+ - 6-Ch 600Vrms Digital Isolator, 2Mbps/50Mbps | Analog Devices

The Analog Devices (formerly Maxim Integrated) MAX14851AEE+ is a six-channel digital isolator delivering 600Vrms isolation with 2Mbps default data rate and a 50Mbps high-speed option in a 16-pin SSOP (QSOP) package. It features monolithic Maxim process technology providing compact, low-cost isolation between circuits operating from independent 3V to 5.5V supplies on each side of the barrier. The device provides a minimum common-mode transient immunity (CMTI) of 3.2 kV/us and is the industry first monolithic 600Vrms digital isolator. A digital isolator is an integrated circuit that transfers logic signals between two voltage domains while maintaining galvanic isolation - a safety barrier that blocks DC and low-frequency AC while allowing high-frequency digital edges to pass. Isolators belong to the signal isolation family, which sits between interface ICs and power management in the broader semiconductor hierarchy. They are essential for breaking ground loops, protecting low-voltage logic from high-voltage transients, and meeting safety standards such as IEC 60747-17 / UL 1577 for reinforced insulation. Key features of the MAX14851AEE+ include six unidirectional channels configurable as forward/reverse combinations, 11.8 ns typical propagation delay, 3V to 5.5V independent supply on each side (suitable as a level translator), 600Vrms working voltage per UL 1577, and an extended -40C to +125C operating temperature range. Independent supply ranges also make the device suitable as a logic-level translator between 3.3V and 5V systems without external circuitry. The MAX14851 uses Maxim's proprietary monolithic isolation process, embedding the isolation barrier on the same silicon die rather than relying on transformer or optical coupling. This monolithic approach achieves lower power consumption and higher channel density than multi-chip alternatives while eliminating the discrete transformer or optocoupler BOM. Typical applications include isolating SPI buses between an MCU and a sensor front-end, isolating I2C and RS-232/RS-485/RS-422 transceivers in industrial fieldbus nodes, general-purpose GPIO isolation in PLC and motor-drive digital interfaces, and level translation between mixed-voltage MCUs and 5V peripherals. Six channels are well matched to 4-wire SPI plus chip-select and one extra GPIO for fault or reset signaling. When designing with the MAX14851AEE+, route the four inner ground pins (GND1/GND2) carefully to maintain barrier creepage and clearance. Place 0.1 uF + 10 uF decoupling on both VDDA and VDDB as close to the IC as possible. Avoid running high-speed traces under the device to preserve creepage on the SSOP body. This page synthesizes distributor pricing, drop-in alternatives, and design notes that are not consolidated in the manufacturer datasheet, including a side-by-side comparison with same-package isolators.

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).

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 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.

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.

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 - 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.

MAX150ACPP

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.

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.
