MAX485EEPA+ - 15kV ESD RS-485 Transceiver | Maxim Integrated
MAX485EEPA+

MAX485EEPA+ - 15kV ESD RS-485 Transceiver | Maxim Integrated

The Maxim Integrated MAX485EEPA+ is a low-power, slew-rate-limited half-duplex RS-485 and RS-422 transceiver with one driver and one receiver, 15 kV ESD protection, and a 4.75 V to 5.25 V supply in an 8-pin PDIP package. It is designed for bidirectional industrial and instrumentation data links where reduced transition rates, overload protection, and reliable differential signaling are important. An RS-485/RS-422 transceiver is an interface IC that converts logic-level signals to and from differential bus voltages. It belongs to the transceiver hierarchy: interface IC -> RS-485/RS-422 transceiver -> differential communication interface. The MAX485EEPA+ combines a transmitter, receiver, driver-enable control, receiver-enable control, and bus pins in one device, reducing the component count required for a bidirectional serial-data link. The MAX485EEPA+ provides one transmit channel and one receive channel. Its 15 kV ESD protection is the principal rugged-environment feature identified in the supplied manufacturer-related data. Slew-rate limiting helps control edge speed and reduce reflected-signal and electromagnetic-interference problems on longer cables. The low-power operating mode also makes the device suitable for equipment where the transceiver remains connected to a bus even when communication is inactive. Communication is established by connecting the differential A and B pins to the twisted-pair bus. The DE input enables the driver, while the active-low RE input enables the receiver. These controls allow the two halves of the transceiver to be disabled independently, supporting point-to-point links, multidrop RS-485 networks, and panel-mounted equipment where a local test loop can be useful. Logic-side signals connect to DI for transmit data and RO for received data. Typical uses include industrial sensor gateways, programmable logic controller interfaces, building-automation equipment, industrial test instruments, and RS-422 links between equipment cabinets. The 5 V supply matches systems that already operate from regulated 5 V rails. Because the device is half-duplex, software or hardware must control bus direction and avoid transmission conflicts when several nodes share the same pair. For reliable operation, route the A and B differential pair as a tightly coupled twisted pair, minimize stub branches, and place termination at physical ends of the bus rather than at every node. Provide local supply decoupling and verify that transceiver-enable timing prevents two drivers from driving the bus simultaneously. Unverified transceiver thresholds, current limits, and exact timing values must be confirmed in the manufacturer datasheet before final release. This product page combines verified distributor descriptions, cross-reference evidence, package and pinout information, replacement guidance, and practical bus-layout considerations. It also distinguishes documented drop-in family options from alternatives that would require a different PCB footprint.

MAX485EESA+ - ±15kV ESD RS-485/RS-422 Transceiver | Analog Devices
MAX485EESA+

MAX485EESA+ - ±15kV ESD RS-485/RS-422 Transceiver | Analog Devices

The Analog Devices (formerly Maxim Integrated) MAX485EESA+ is a 5V, half-duplex, slew-rate-limited RS-485/RS-422 transceiver in an 8-pin SOIC (SO-8) package, featuring ±15kV ESD protection on the bus pins for harsh industrial environments. It integrates one driver and one receiver, supports data rates up to 2.5 Mbps, and operates from a single 5V supply drawing 1 mA (typical) quiescent current while allowing up to 32 transceivers on the bus. The slew-rate-limited driver minimizes EMI and reflections on improperly terminated cables, enabling error-free transmission over twisted-pair media up to 1200 m. The MAX485EESA+ includes ±15kV HBM ESD protection on the driver output and receiver input pins, making it suitable for hot-swap and field-bus installations where cable discharge events are common. An RS-485/RS-422 transceiver is a differential line driver/receiver IC that converts a single-ended TTL/CMOS logic signal into a balanced differential pair suitable for transmission over twisted-pair cabling. RS-485 supports multi-drop (up to 32 unit loads, 256 with newer parts) half-duplex communication across long distances; RS-422 is a point-to-point full-duplex standard. The MAX485EESA+ belongs to the half-duplex RS-485 transceiver class within the larger interface-IC category of wired communication semiconductors. Key features include ±15kV HBM ESD protection, slew-rate-limited driver for low EMI, 1/2 unit-load input impedance, thermal-shutdown protection, and short-circuit current limiting. The receiver provides fail-safe operation, guaranteeing a logic-high output when the bus inputs are open, shorted, or idle, eliminating the need for external biasing resistors at the ends of the cable. Current limiting and thermal shutdown protect the driver outputs against excessive power dissipation caused by bus contention or output short circuits to ground or supply. Typical applications include industrial field-bus networks (Modbus, Profibus, DMX512), building automation (BACnet, LonWorks), HVAC controls, security systems (access control, alarm panels), and point-of-sale (POS) equipment. The wide operating temperature range (-40 °C to +85 °C for the E grade) and rugged ESD rating make it a drop-in solution for industrial controllers, PLCs, and motor-drive interfaces. When designing with this device, place 100 nF bypass capacitors as close as possible to VCC (pin 8) and provide a 120 Ω termination resistor at each end of the bus when using the highest data rates. Keep the PCB stub length to the connector below one-tenth of the driver rise time to minimize reflection-induced jitter. Use twisted-pair cable with 100 Ω characteristic impedance (e.g., Belden 3106A) and avoid running RS-485 traces parallel to noisy switching rails.

MAX485EESA+T - 2.5Mbps RS-485 Transceiver | Analog Devices
MAX485EESA+T

MAX485EESA+T - 2.5Mbps RS-485 Transceiver | Analog Devices

Analog Devices MAX485EESA+T is a 5 V, half-duplex RS-485 and RS-422 transceiver with a maximum data rate of 2.5 Mbps, slew-rate-limited driver outputs, and ±15 kV ESD protection, housed in an 8-pin SOIC package. A transceiver IC combines a differential line driver and receiver on one die, allowing a digital UART signal to travel over a balanced, noise-resistant bus. The MAX485 family belongs to the interface IC hierarchy: RS-485 transceiver → differential transceiver → wired-communication interface IC → semiconductor. Its half-duplex architecture supports bidirectional communication by sharing one differential pair and changing direction through the driver-enable and receiver-enable controls. The MAX485EESA+T combines a 4.75 V to 5.25 V supply range with a 2.5 Mbps maximum data rate. Its slew-rate-limited driver reduces unwanted high-frequency energy on the bus, while ±15 kV ESD protection strengthens the interface against electrostatic discharge encountered in industrial environments. The low-power design also supports systems where the transceiver must remain connected to a 5 V control rail. Operationally, the device provides separate receive-enable and driver-enable inputs, allowing the receiver to remain active while transmission is disabled. The receiver converts differential bus voltage into a logic-level output, while the driver converts a logic-level input into differential A and B outputs. This arrangement supports both point-to-point links and multi-drop RS-485 networks when termination and biasing are designed correctly. Typical applications include industrial control networks, building automation, instrumentation links, data acquisition systems, motor controllers, and factory communication equipment. The MAX485EESA+T is especially appropriate for factory environments where ESD exposure, long cable runs, and grounded or ungrounded equipment can create substantial bus-level transients. PCB design should preserve the pinout and provide the decoupling, protection, and termination required by the bus. Place the VCC bypass capacitor close to the supply pin, route the differential pair as a balanced pair, and use a protection network designed for the expected surge and ESD environment. Avoid long unprotected stubs because they can create impedance discontinuities and reflections. This product page combines the manufacturer-datasheet specifications, verified package and cross-reference information, drop-in alternatives, and application-focused engineering guidance. It is structured to support component selection, PCB replacement planning, and RS-485 interface design rather than only basic part identification.

MAX485EPA+ - 2.5Mbps RS-485/RS-422 Transceiver | Maxim Integrated
MAX485EPA+

MAX485EPA+ - 2.5Mbps RS-485/RS-422 Transceiver | Maxim Integrated

The Analog Devices Inc./Maxim Integrated MAX485EPA+ is a low-power RS-485/RS-422 interface transceiver with one driver and one receiver, a 2.5 Mbps maximum signaling rate, and an 8-pin PDIP package. It is designed for industrial, instrumentation, and distributed-control links that require reliable differential data transmission over longer cable runs. The verified listing identifies the device as a half-duplex RS-422/RS-485 transceiver with a 4.75 V to 5.25 V supply range. An RS-485/RS-422 transceiver is an interface IC that converts logic-level digital signals into differential bus signals and converts received differential signals back into CMOS-compatible logic. RS-422 and RS-485 use differential signaling to improve noise immunity and allow communication across cables in electrically noisy environments. The MAX485EPA+ supports one driver and one receiver, making it suitable for point-to-point, multidrop, and half-duplex bus arrangements when the system includes the required enable control, termination, biasing, and transceiver-direction logic. The MAX485EPA+ is specified as a low-power transceiver with driver short-circuit current limiting and protection. The verified product data states that the output slew rate is not limited and that the device can transmit up to 2.5 Mbps. This speed capability makes it useful for factory automation, industrial control, building automation, and embedded communications where the bus must carry bursts of digital data while maintaining a compact, widely available 8-pin through-hole package. The device is suitable for RS-485 networks connected to microcontrollers, sensors, motor controllers, data converters, and remote I/O modules. The system designer must account for bus topology, cable length, termination resistors, common-mode limits, grounding, and the direction-control interface. The MAX485EPA+ does not by itself provide galvanic isolation; applications requiring isolation between high-energy bus wiring and control electronics should add suitable isolation components and protection devices. Because the MAX485EPA+ uses a PDIP package, it is particularly useful for prototypes, serviceable equipment, and industrial products assembled through-hole rather than high-density automated surface-mount processes. The 8-pin package simplifies inspection and rework. The plus suffix identifies the leaded product ordering code shown in the verified distributor records; package, temperature, and qualification requirements should still be checked against the exact manufacturer ordering information before production release. This page combines verified distributor listings, manufacturer-family information, pricing context, and practical interface design guidance. It is intended to help engineers identify whether the MAX485EPA+ fits an existing RS-485 or RS-422 PCB and to distinguish it from alternatives with different package, speed, supply, or protection characteristics.

MAX485ESA+ - 5V RS-485/RS-422 Transceiver, 2.5Mbps, SOIC-8
MAX485ESA+

MAX485ESA+ - 5V RS-485/RS-422 Transceiver, 2.5Mbps, SOIC-8

The Analog Devices (formerly Maxim Integrated) MAX485ESA+ is a low-power, slew-rate-limited RS-485/RS-422 transceiver housed in an 8-pin SOIC package. The device contains one driver and one receiver, operates from a single 5 V supply, and supports data rates up to 2.5 Mbps with half-duplex communication. It draws between 120 µA and 500 µA of supply current when unloaded or fully loaded with disabled drivers, making it well suited for power-sensitive industrial networks. What is an RS-485/RS-422 transceiver? An RS-485 transceiver (TIA/EIA-485) is a differential line driver/receiver IC that converts a single-ended TTL/CMOS logic signal into a balanced differential signal suitable for transmission over twisted-pair cabling. RS-485 transceivers belong to the broader physical-layer IC family inside Interface ICs, which also includes RS-232, CAN, and I2C transceivers. The half-duplex variant shares one differential pair between driver and receiver, reducing cable cost for bidirectional buses such as Profibus, Modbus RTU, and DMX512. Key features of the MAX485ESA+ include a 1/8 unit-load input impedance (allowing up to 256 transceivers on a single bus), driver short-circuit current limiting, and thermal-shutdown protection that places the driver outputs into a high-impedance state. The receiver includes a fail-safe function that guarantees a logic-high output when the differential input is floating, shorted, or terminated but idle. Industry-standard SOIC-8 pinout and 5 V operation make the part a drop-in upgrade or replacement for legacy Maxim/Intersil RS-485 designs. Internally, the driver uses a slew-rate-limited output stage to reduce EMI and reflections on unterminated cables, while the receiver incorporates hysteresis and an input filter to reject common-mode noise. The common-mode input voltage range extends from -7 V to +12 V relative to ground, supporting long cable runs with significant ground potential differences between nodes. Typical applications include industrial field-bus networks (Modbus, Profibus, BACnet), building automation, HVAC controllers, motor-control command links, point-of-sale terminals, and multidrop RS-485 utility metering. Designers select the MAX485ESA+ when they need a proven, second-source-friendly 5 V half-duplex transceiver with long-term availability. When designing with this part, place 120 Ω termination resistors only at the two physical ends of the bus to avoid loading the drivers. Use a 100 nF decoupling capacitor placed within 5 mm of the VCC pin, and route the A/B differential traces with controlled 100 Ω differential impedance and ground-referenced return paths. This page synthesizes distributor pricing, drop-in compatible alternatives (including the SN75176B and SP485EN-L/TR families), and practical design notes that go beyond the bare datasheet, helping engineers select and source the right transceiver faster.

MAX485ESA+T

MAX485ESA+T - 2.5Mbps RS-485/RS-422 Transceiver | ADI

Analog Devices MAX485ESA+T is a low-power half-duplex RS-485/RS-422 interface transceiver with one driver and one receiver, a maximum data rate of 2.5Mbps, and a 4.75V to 5.25V supply range. The device is supplied in an 8-pin SOIC package and is intended for industrial bidirectional serial-data links. An RS-485 transceiver is an interface IC that combines a differential line driver and differential receiver. These transceivers connect a host controller, PLC, sensor, or industrial endpoint to a balanced communication bus. The RS-485 standard hierarchy supports longer, noise-resistant interconnects than single-ended interfaces, while RS-422 compatibility allows the same device family to serve point-to-point links. Driver enable and receiver-enable inputs provide local control over bus direction and reception. The MAX485ESA+T uses a 4.75V to 5.25V supply and supports data rates up to 2.5Mbps. Its driver is short-circuit-current limited and protected, an important feature when a bus fault drives a line into a low-impedance condition. The integrated receiver converts differential bus voltage into a logic-level output, while the driver converts logic-level data into differential output. This combination supports half-duplex operation, in which the same pair of conductors carries transmitted and received data at different times. The 8-pin SOIC package keeps the implementation compact and familiar to industrial-control board designers. Because the MAX485ESA+T does not limit its slew rate, it can transmit at up to 2.5Mbps according to the provided manufacturer and distributor documentation. That speed is useful for factory automation, instrumentation, and embedded control networks, although cable length, termination, topology, and signal integrity become increasingly restrictive as data rate rises. Typical uses include RS-485 fieldbus connections, motor-control diagnostics, industrial sensor gateways, building-control equipment, and communications between a microcontroller and remote peripheral. In a typical circuit, the transceiver sits between a UART-capable controller and a protected, twisted-pair bus. A termination resistor is placed at each end of the bus, while common-mode protection and chassis-grounding practices may be needed in electrically noisy installations. Designers should verify that the selected cable length and topology can support the intended 2.5Mbps rate, connect the receiver and driver enables for the required half-duplex behavior, and maintain compatible logic levels across the system. The 5V supply requirement also requires a 4.75V to 5.25V regulator rather than a 3.3V rail. This page combines the verified manufacturer and distributor information with package-level engineering guidance, practical interface considerations, pricing context, and pin-compatible replacement analysis to support faster component selection and PCB migration.

MAX485MJA

MAX485MJA - 2.5 Mb/s RS-485/RS-422 Transceiver, 8-CERDIP | Analog Devices

The Analog Devices MAX485MJA is a 1/1 half-duplex RS-485/RS-422 interface transceiver rated for 2.5 Mb/s data rate, packaged in an 8-pin CERDIP military-grade ceramic dual-inline package. Each device contains one driver and one receiver, providing a complete differential bus interface on a single die. An RS-485 transceiver is the physical-layer bridge between a logic-level UART or microcontroller and a balanced, multi-drop cable bus. RS-485 belongs to the differential signaling family of interface ICs, sitting between the transceiver category and the wider Interface ICs > Drivers/Receivers/Transceivers hierarchy. Because differential signaling sends a signal and its complement over a twisted pair, it rejects common-mode noise, allows long cable runs, and supports multiple nodes on one bus, making it the de facto standard for industrial automation, building controls and instrumentation networks. Key features of the MAX485MJA include a low-power slew-rate-limited driver that reduces EMI and ringing on slow edges, one driver and one receiver per package, and a 2.5 Mb/s data rate as listed by distributors for the MAX485 series. The /RE and DE pins give the designer independent control over driver enable and receiver enable, allowing half-duplex bus turnaround control from a single microcontroller pin. Operating over the extended industrial temperature range, the CERDIP-8 mechanical format gives long-term availability for rugged and legacy industrial platforms. The device implements a classic current-mode differential driver with a failsafe bias network so that an unpowered or disconnected node does not clamp the bus, plus a fail-safe receiver stage that interprets an open or shorted bus as a defined logic state. The 8-pin pinout (RO, /RE, DE, DI, GND, A, B, VCC) is shared across the entire MAX48x family, which simplifies cross-referencing and second sourcing across ceramic, plastic and surface-mount variants. Typical applications include industrial RS-485 field buses such as Modbus RTU networks, building HVAC and lighting controllers, PLC and data-acquisition module interfaces, POS terminals and industrial instrumentation, and retrofit of legacy 2.5 Mb/s RS-485 equipment where a ceramic military-temperature package is required. When designing with the MAX485MJA, note that the 8-pin package leaves no dedicated fail-safe bias resistor footprint; many designs add 100 ohm to 220 ohm termination resistors and a fail-safe bias network externally. Because the CERDIP-8 body is larger than a standard PDIP-8, check board mechanicals and pin-hole spacing, and keep the A and B differential pair away from switching nodes and high-current returns to preserve common-mode margin. This page consolidates verified distributor pricing, a drop-in cross-reference set, pin-level detail and applied design guidance that is not available from a single manufacturer datasheet, helping engineers qualify this part quickly for both new and legacy industrial designs.

MAX487ESA+

MAX487ESA+ - Low-Power Slew-Rate-Limited RS-485/RS-422 Transceiver | Analog Devices

The Analog Devices MAX487ESA+ is a low-power, slew-rate-limited RS-485/RS-422 transceiver containing one driver and one receiver in an 8-pin SOIC (NS) package. It operates from a single 5V supply, supports data rates up to 250 kbps, and provides ±15 kV ESD protection on driver output and receiver input pins. The MAX487ESA+ features low quiescent supply current (120 µA to 500 µA) under load and 0.1 µA in shutdown, making it ideal for power-sensitive multi-drop networks. An RS-485 transceiver is a differential line driver/receiver that translates logic-level UART signals to a robust differential signal capable of being transmitted over long cables in electrically noisy environments. RS-485 supports multi-drop configurations of up to 32 transceivers on a single twisted pair, enabling half-duplex or full-duplex communication over distances up to 1200 m. RS-485 transceivers belong to the broader interface IC category within power management and communication ICs, and are standardized under TIA-485 (formerly EIA-485). Key features include slew-rate-limited driver outputs that reduce EMI and reflections on unterminated or improperly terminated cables, true fail-safe receiver inputs that guarantee a known output state when the bus is idle or shorted, and a low-current shutdown mode that places the device in <0.1 µA quiescent for power-saving operation. The MAX487ESA+ carries ±15 kV HBM ESD protection on the bus pins, providing robust tolerance to electrostatic discharge events during handling and field installation. The MAX487ESA+ integrates a complete half-duplex RS-485 link layer with internal cable termination management through slew-rate control rather than discrete termination. Its 5V single-supply operation simplifies power architecture in industrial 24V-rail-derived systems, and its robust differential signaling supports industrial control, building automation, and point-of-sale applications. Typical applications include industrial fieldbus networks (Modbus, Profibus), HVAC building automation systems, motor control encoder feedback, point-of-sale (POS) terminals, security system intercom panels, and remote utility metering. The MAX487ESA+ pinout and protocol match the broader MAX481/MAX483/MAX485/MAX487/MAX1487 family, allowing drop-in upgrades and obsolescence mitigation across existing designs. Design considerations: include a 100 nF decoupling capacitor close to VCC, place a 120 Ω termination resistor across the differential pair only at the cable ends, and ensure the cable shield is grounded at one end only to suppress ground loops. The DE and RE pins control driver/receiver direction; when using half-duplex, tie DE and /RE together with a single GPIO line. This page synthesizes distributor inventory, parametrically matched drop-in alternatives from the MAX48x family and competitive second sources, and practical design notes that go beyond what the manufacturer datasheet alone provides.

MAX6816EUS+T - ±15kV ESD SOT-143-4 Switch Debouncer | Maxim
MAX6816EUS+T

MAX6816EUS+T - ±15kV ESD SOT-143-4 Switch Debouncer | Maxim

The Analog Devices / Maxim Integrated MAX6816EUS+T is a single-channel CMOS switch debouncer IC housed in a 4-pin SOT-143-4 surface-mount package, qualified over a 2.7 V to 5.5 V supply range and engineered for clean interfacing of mechanical switches to digital logic. It delivers a clean, debounced logic output from one bouncing mechanical input at 25 µA quiescent current with ±15 kV ESD protection on the switch input. A switch debouncer is a specialized interface IC that filters the mechanical contact bounce of switches, keypads, relays, or other electro-mechanical contacts so a downstream microcontroller or ASIC receives a single, deterministic logic transition. As a subcategory of supervisory / interface ICs, switch debouncers sit between the analog-mechanical input domain and the digital domain; they belong to the broader interface-IC hierarchy (specialized interface -> interface IC -> integrated circuit) and serve the same role as a hardware RC filter plus Schmitt trigger, but in a single chip. Key features of the MAX6816EUS+T include a fixed 40 ms (typical) debounce qualification delay that removes both switch opening and closing bounce, ±15 kV HBM ESD protection on the switch input per IEC 61000-4-2 air-discharge testing, 2.7 V to 5.5 V single-supply operation, low 25 µA quiescent current, and a small SOT-143-4 outline. The output stage is a CMOS push-pull driver capable of sourcing/sinking several milliamps, so it can directly drive most CMOS logic families without an external pull-up resistor. The MAX6816/MAX6817/MAX6818 family is fabricated on a low-power CMOS process with on-chip ESD cells and a precision timer block that sets the debounce interval without external capacitors. Compared to discrete RC + Schmitt debounce networks, the integrated timer is stable across temperature and removes the need for tuning. The MAX6818 (octal, 20-pin) is pin-compatible with the LS573 octal latch (except for the CH pin), giving a migration path for designers scaling from 1 channel to 8 channels. Typical applications of the MAX6816EUS+T include membrane keypad interfaces, pushbutton reset circuits, industrial control panels, automotive body controllers, portable consumer electronics, and appliance front-panel switches. The compact SOT-143-4 footprint makes it suitable where board area is constrained. When designing with this part, place a 0.1 µF decoupling capacitor within 5 mm of the VCC pin and keep the trace from the mechanical switch to the IN pin short to maximize ESD protection effectiveness. The output does not require a pull-up resistor. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes beyond what the manufacturer datasheet alone provides.

MAX71071+

MAX71071+ - 24-Bit Dual-Channel Isolated Metrology ADC | Maxim Integrated

The Maxim Integrated MAX71071+ (now under Analog Devices) is a 24-bit, dual-channel, isolated analog-to-digital converter (ADC) designed for high-precision metrology applications. Housed in a 10-pin uMAX/uSOP surface-mount package, the device pairs with a compatible MAX71xxx host to provide simultaneous current and voltage measurements. The host supplies control, command, and isolated power, while a pulse transformer provides the isolated data and clock path between the device and host, eliminating the need for additional optocouplers or digital isolators in the measurement subsystem. A metrology ADC is a high-resolution data converter optimized for energy metering, power-quality monitoring, and revenue-grade instrumentation. Compared with general-purpose ADCs, metrology converters emphasize DC accuracy, wide dynamic range, low noise, and excellent linearity over industrial temperature ranges. The MAX71071+ sits in the converter hierarchy as: ADC -> data converter -> signal chain IC -> analog/mixed-signal semiconductor. Key features include 24-bit resolution across two input channels, an integrated isolated interface through the host pulse transformer, simultaneous sampling of voltage and current channels, and a small 10-pin uSOP/uMAX footprint suitable for compact, isolated current-sensing modules. The device supports industrial temperature grades and is targeted at smart-meter, sub-metering, and power-monitoring designs where galvanic isolation and high accuracy are mandatory. The MAX71071+ uses an isolated SPI/dual-wire interface to the host, removing the requirement for external digital isolators. This architecture reduces BOM count, board area, and design complexity for isolated energy-measurement front ends. The companion host MAX71xxx device provides the isolated power rail to the secondary side via the pulse transformer, which also carries the bidirectional data between host and ADC. Typical applications include single-phase and polyphase electricity meters, branch-circuit power monitors, isolated current-sensing modules for industrial equipment, solar inverter string monitors, EV charging-station energy meters, and smart power strips. The integrated isolation simplifies safety compliance for line-voltage measurements. When designing with the MAX71071+, follow the datasheet reference layout for the pulse transformer and keep the secondary-side bypass network within the recommended geometry. A [DATA_NEEDED: full input bandwidth / sample rate] and [DATA_NEEDED: effective number of bits / SINAD] should be confirmed from the datasheet, since the available web snippets did not include complete AC performance numbers.

MAX71071+T

MAX71071+T - Dual 24-Bit Isolated ADC | Analog Devices

Analog Devices MAX71071+T is a dual-channel isolated 24-bit analog-to-digital converter designed for metrology measurements of current and voltage. The device communicates with a compatible MAX71xxx host through an integrated pulse-transformer isolation path and is supplied in a 10-uMAX/uSOP package. Its two measurement channels and isolated data, clock, and power interface support isolated sensing systems. An isolated ADC is an analog-to-digital converter whose measurement side is electrically separated from the control and processing side. This isolation limits the transfer of unwanted voltage and current between a high-voltage or high-current measurement environment and the host electronics. Within the signal-chain hierarchy, the MAX71071+T is a data-acquisition IC, an isolated ADC, and ultimately a metrology measurement component. The MAX71071+T provides two measurement inputs, 24-bit resolution, and simultaneous isolation through a pulse transformer. The pulse transformer carries the isolated data, clock, and power path, reducing the need for separate isolation components in the measurement subsystem. The host retains responsibility for control commands and the associated power supplied toward the measurement interface. This architecture is intended to measure current and voltage while maintaining an isolation barrier between the sensed quantities and the host. The exact input ranges, accuracy figures, sampling rate, power requirements, channel multiplexing arrangement, and timing characteristics should be confirmed against the relevant MAX71071 manufacturer documentation before setting the analog front end and system timing. Typical uses include isolated current monitoring, isolated voltage measurement, industrial metering equipment, power-system instrumentation, and other metrology systems that pair the converter with a compatible MAX71xxx host. The isolated interface is particularly useful when the measured circuit and the controller must remain galvanically separated. Designers should begin with the host-interface requirements, supported input ranges, and isolation ratings. Transformer-based isolation imposes timing and layout considerations around the measurement side, while host-side routing must preserve clock and data signal integrity. Component values, filtering, grounding, and creepage requirements should be derived from the application voltage, current, bandwidth, and safety environment. This product page combines the manufacturer product information, distributor listings, family relationships, and practical selection guidance to clarify where the MAX71071+T belongs in an isolated metrology design. It also distinguishes documented functions from parameters that require engineering confirmation before layout release.

MAX7219CNG - 8-Digit LED Display Driver, 24-PDIP | Maxim

The Analog Devices (formerly Maxim Integrated) MAX7219CNG is a compact, serial-input/output common-cathode LED display driver that interfaces microprocessors to 7-segment numeric LED displays of up to 8 digits, bar-graph displays, or 64 individual LEDs. Housed in a 24-pin PDIP (narrow, 0.300 inch / 7.62 mm) through-hole package, the device operates from a single +4.0 V to +5.5 V supply and includes on-chip BCD Code-B decoder, multiplex scan circuitry, segment and digit drivers, plus an 8x8 static RAM that stores the display state. A serial-in/serial-out LED driver is an interface IC that translates a high-speed synchronous serial data stream (SPI/QSPI/Microwire compatible on MAX7219) into multiplexed constant-current segment and digit outputs, eliminating the need for external current-limiting resistors on every LED. The MAX7219 belongs to the broader hierarchy LED display driver > display driver IC > interface IC > integrated circuit > semiconductor. Its integrated BCD decoder, multiplexing scan engine, and per-segment current control place it in the same functional family as the MAX7221 (SPI-only variant) and competitors such as Holtek HT16K33 and Titan Micro TM1637. Key features of the MAX7219CNG include an individual LED segment current programmable up to 40 mA per segment via a single external resistor (ISET), a 150 µA low-power shutdown mode (data retained), a scan-limit register that allows 1 to 8 digits, a digital brightness control (16 steps via 4-bit PWM duty cycle), and a display test mode that forces all segments on. The serial interface runs up to 10 MHz at +5 V, and the device cascades for additional digits by clocking the DOUT pin into the DIN of the next MAX7219. Typical applications are 8-digit 7-segment numeric readouts, 8x8 LED matrix modules (two cascaded MAX7219s drive a 64-LED matrix), bar-graph displays, industrial panel meters, scoreboard displays, and Arduino/AVR/PIC-based user interfaces. The MAX7219 is essentially the de-facto standard for hobbyist and educational LED matrix projects, with mature open-source libraries (LedControl, MD_MAX72XX, MD_Parola) supporting it. When designing with the MAX7219CNG, place a 0.1 µF bypass capacitor close to V+ and a 10 µF tantalum bulk capacitor on the supply rail, keep the ISET resistor within 9.53 kΩ (40 mA per segment) to 47 kΩ (10 mA per segment), and respect the 6 V absolute-maximum V+ rating. The narrow PDIP-24 footprint is identical to the MAX7221CNG and MAX7219CNG+ RoHS-compliant variant, so PCBs can be designed once and populated with either part.

MAX7456EUI+T

MAX7456EUI+T - Monochrome OSD Generator with EEPROM, 28-TSSOP-EP | Analog Devices

The Analog Devices (formerly Maxim Integrated) MAX7456EUI+T is a single-channel monochrome on-screen display (OSD) generator integrated circuit that combines a 256-character font ROM, non-volatile character memory (NVRAM), video sync separator, video driver, and SPI-compatible serial interface in a single 28-pin TSSOP-EP package. Designed for NTSC and PAL video systems, the MAX7456EUI+T displays up to 256 user-programmable 12x18-pixel characters at row 1 (top of frame), row 14 (middle), or row 26 (bottom), and integrates a video output driver that delivers a 2 Vp-p composite signal directly into a 75 ohm terminated load. An OSD (on-screen display) generator is a specialized mixed-signal IC that overlays text, graphics, and icons onto a composite video stream in applications where a graphical overlay is required without a full graphics controller. The MAX7456EUI+T belongs to the video processing IC family within the broader signal-chain and display-driver semiconductor hierarchy. It serves markets requiring character-based overlays in security camera menus, drone telemetry, industrial HMI, and consumer VCR/DVD equipment, eliminating the need for external video drivers, sync separators, switches, and EEPROM storage. This integration lowers system BOM cost, PCB area, and design risk. Key differentiating features include on-chip 256-character NVRAM (no external EEPROM required), built-in video output buffer (saves an op-amp), integrated sync separator for composite video or separate sync input, SPI serial control interface (compatible with 3.3 V and 5 V microcontrollers), and 2 Vp-p output drive into 75 ohm. The device operates from a single 5 V analog supply with a separate 3.3 V digital supply, supports 256 user-programmable characters, and provides automatic NTSC/PAL detection with 9.6 kB/s maximum character upload rate. Architecturally, the MAX7456EUI+T combines an analog video path (sync separator, clamp, video DAC, output buffer) with a digital control section (character memory, font ROM, address registers, SPI slave). The on-chip NVRAM uses Maxim's Zener-based non-volatile memory technology, which the manufacturer notes has a limited write endurance (specified in the datasheet). Designers should treat the NVRAM as configuration storage, not as a high-cycle-count working buffer. Typical applications include closed-circuit television (CCTV) and IP camera menu overlays, FPV drone OSD for telemetry and flight data, industrial machine vision HMI, set-top box user interface overlays, consumer VCR/DVD on-screen menus, and avionics or marine instrumentation display overlays. The MAX7456EUI+T suits any video-based system that needs non-volatile, persistent on-screen information without a full graphics processor. When designing with this device, verify NVRAM write endurance against expected menu-update frequency, and provide adequate decoupling on both the analog 5 V (VDD) and digital 3.3 V (VDD_DIG) rails to suppress switching noise coupling into the analog video output. Designers should also confirm the upstream video source provides proper sync polarity, as the MAX7456EUI+T expects NTSC/PAL standard composite video or separate HSync/VSync inputs. This page synthesizes distributor pricing, lifecycle status, and cross-reference guidance for the MAX7456EUI+T, including identification of the third-party AT7456E clone marketed as a drop-in substitute on certain distributor channels, and engineering considerations for transitioning away from this obsolete part.

MAX9100EUK+T - 1.0V 5µA Micropower Comparator | Analog Devices
MAX9100EUK+T

MAX9100EUK+T - 1.0V 5µA Micropower Comparator | Analog Devices

The Analog Devices MAX9100EUK+T is a single-supply micropower voltage comparator with 1.0V to 5.5V operation, 5µA quiescent current, and a 5-pin SOT-23 package. It is designed for battery-powered systems that require low-voltage decision-making without the higher supply requirement or current consumption of conventional comparators. A micropower comparator is a voltage-regulator-family analog semiconductor that compares two input voltages and produces a push-pull logic output indicating their relationship. The MAX9100 belongs to the comparator hierarchy and is used as a simple decision element, protection element, or threshold detector between an analog sensor and a digital system. Its low supply voltage and low quiescent current make it suitable for single-cell and coin-cell powered equipment. Key features include operation from a single 1.0V to 5.5V supply, 5µA quiescent current, rail-to-rail input capability, and an open-drain output according to the manufacturer comparison information. The common-mode input range includes the negative supply rail, which helps monitor low-voltage battery signals. The MAX9100EUK+T is specified in the 5-pin SOT-23 package and is supplied in tape-and-reel packaging. The MAX9100 is intended for low-energy signal-chain designs where the comparator must operate directly from a depleted battery or regulated low-voltage rail. Because its supply range begins at 1.0V, it can remain useful as the battery approaches its discharge endpoint. The device is optimized for single-cell systems rather than high-voltage industrial comparison tasks. Typical applications include battery threshold detection, portable sensor interfaces, low-voltage power sequencing, window or level comparison, and simple over-discharge indication. In these systems, the comparator can establish whether a measured voltage is above or below a reference without requiring a powered analog front end with a higher minimum supply. Designers should verify the exact output topology, input limits, propagation delay, and operating-temperature ratings against the current manufacturer datasheet before layout. Input and supply decoupling should be placed close to the device, and unused comparator inputs must not be left floating. The manufacturer application information is the authoritative reference for electrical limits and recommended usage. This product page combines verified manufacturer and distributor information with practical application guidance, pricing context, and design considerations that help engineers evaluate the MAX9100EUK+T for low-voltage battery systems.

MAX942CUA+T - 80ns High-Speed 3V/5V Comparator | Maxim
MAX942CUA+T

MAX942CUA+T - 80ns High-Speed 3V/5V Comparator | Maxim

The Analog Devices / Maxim Integrated MAX942CUA+T is a single high-speed, low-power comparator optimized for 3V or 5V single-supply systems, housed in an 8-pin µMAX (uSOP) package. It combines 80 ns propagation delay with only 3 mA supply current per comparator and true rail-to-rail inputs that extend 200 mV beyond the rails. The CMOS push-pull / TTL-compatible output stage eliminates the need for an external pull-up resistor and swings rail-to-rail on the output side as well. A comparator is an analog decision-making element that compares two input voltages and drives its output to one of two saturated states; it is the 1-bit ADC of the analog domain, often used to translate an analog level into a digital logic edge for a microcontroller, ASIC, or FPGA. Comparators sit in the broader linear IC hierarchy: analog building block -> op-amp/comparator -> high-speed comparator -> rail-to-rail input comparator -> single-supply part. The MAX941/MAX942/MAX944 family from Maxim occupies the 3V/5V rail-to-rail comparator node of that hierarchy and is widely cited as the reference for low-power, fast-responding comparators in commercial-grade designs. Key features of the MAX942 include a 3 mV typical input offset voltage, 150 nA typical input bias current, 80 ns propagation delay, 3 mA supply current per comparator, push-pull CMOS/TTL-compatible output, and operation from 2.7 V to 5.5 V. It is specified over the 0 °C to +70 °C commercial temperature range in the MAX942CUA+T (uSOP-8) variant and is offered in tape-and-reel packaging with the +T suffix. The MAX942 uses a standard high-speed comparator architecture with input ESD-protection diodes, a low-offset input stage, and a CMOS push-pull output driver. The rail-to-rail input stage uses an N-channel / P-channel complementary differential pair that switches automatically as the common-mode voltage crosses the mid-supply region, preserving low distortion across the entire input range including 200 mV beyond VCC and GND. The push-pull output swings within millivolts of both rails for direct interfacing to 3V/5V CMOS logic. Typical applications include window detectors, threshold detectors, zero-crossing detectors, A/D front-ends, and line receivers in portable, industrial, and instrumentation equipment. Because the inputs remain linear 200 mV beyond both rails, the MAX942 is well suited to monitor a 5 V rail with a 5.5 V reference or to sense signals near ground with a single-supply design. When designing with this part, observe the absolute-maximum input current limit on the input ESD diodes and add a series resistor if a large overdrive is expected. The push-pull output cannot be wire-ORed with other open-drain outputs - if a shared interrupt line is needed, choose the open-drain MAX941 instead.

MAX9611AUB+ - 12-Bit High-Side Current-Sense Amplifier | Analog Devices
MAX9611AUB+

MAX9611AUB+ - 12-Bit High-Side Current-Sense Amplifier | Analog Devices

The Analog Devices MAX9611AUB+ is a high-side current-sense amplifier with an integrated 12-bit ADC and a configurable op amp or comparator gain block, operating from a 0V to 60V input common-mode range and offered in a 10-pin uMAX package. A high-side current-sense amplifier is an analog measurement IC that develops a voltage proportional to the current passing through a sense resistor placed in a supply or power rail. It belongs to the current-sense amplifier hierarchy within signal-chain and power-management semiconductors. By measuring voltage across a small shunt, the device enables current monitoring, protection, diagnostics, and feedback without interrupting the high-side load path. Key verified features include a 0V to 60V input common-mode range, programmable full-scale voltages of 440mV, 110mV, and 55mV, a 12-bit ADC, and 2.5MHz bandwidth identified in distributor product data. The MAX9611AUB+ uses the noninverting configuration identified by Analog Devices. Its integrated ADC supports digital current measurement, while the gain block can support comparator-style threshold functions according to the device documentation. The combination of a wide common-mode range and selectable full-scale voltage allows the sense resistor to be selected for the expected current range. This is useful when current measurements must operate across automotive, industrial, or power-supply rails while preserving measurement resolution. The 60V capability also exceeds the nominal range of many low-voltage signal-chain amplifiers, allowing the part to remain on a higher-voltage high-side rail. Typical applications include motor and actuator current monitoring, battery-pack current sensing, industrial power-system protection, DC-DC converter feedback, and automotive load diagnostics. The noninverting MAX9611 is appropriate when the measured output polarity and system architecture match the target board. Designers should verify the sense-resistor value, full-scale setting, ADC reference, Kelvin routing, filtering, and thermal dissipation before production. The manufacturer’s application guidance and datasheet should control the final values because the provided source data does not include all timing, accuracy, and electrical limits. This page consolidates verified manufacturer and distributor information, explains practical current-sense design choices, and distinguishes documented alternatives from unverified package substitutions.

MAX9675ECQ+ - 110MHz 16x16 Video Crosspoint Switch | Maxim Integrated
MAX9675ECQ

MAX9675ECQ+ - 110MHz 16x16 Video Crosspoint Switch | Maxim Integrated

The Analog Devices (formerly Maxim Integrated) MAX9675ECQ+ is a nonblocking 16 x 16 video crosspoint switch with buffered inputs and outputs, programmable gain, and a 110 MHz bandwidth. It is housed in a 100-pin TQFP (14x14 mm) package and operates from a single 2.7 V to 5.5 V supply, drawing a low quiescent current suited to multi-channel video routing cards and large switching arrays. A video crosspoint switch is an analog or digital signal-routing IC that allows any of N inputs to be switched to any of M outputs, typically with buffering on both sides so signals can drive long PCB traces or 75 ohm video loads. Crosspoint switches sit at the heart of video routers, production switchers, surveillance multiplexers, and broadcast equipment, replacing mechanical relays and discrete video amplifiers with a single silicon device. Programmable gain lets the designer compensate for cable losses or output-load variations across channels. The MAX9675ECQ+ integrates sixteen buffered inputs and sixteen buffered outputs with a fast SPI/QSPI-compatible 3-wire serial interface for matrix mode and per-channel gain programming. The BiCMOS process supports rail-to-rail video swings and wide bandwidth at low quiescent power, while on-chip clamp and bias circuitry preserves AC-coupled video baselines. All outputs are held in a high-impedance disabled state during power-up to avoid signal contention in multi-device arrays. Typical applications include broadcast video routers, professional video switchers, security and surveillance multiplexers, medical imaging pipelines, automotive infotainment video backbones, and test-and-measurement video generators. The wide supply range (2.7 V to 5.5 V) makes it compatible with both 3.3 V and 5 V logic, while the 110 MHz -3 dB bandwidth easily handles SD-SDI, composite, component, and RGBHV video formats. When designing, AC-couple inputs and outputs with 220 uF electrolytics and 0.1 uF ceramics, keep ground returns short and wide to preserve 110 MHz flatness, and program gain conservatively at +1 (0 dB) for cable-compensated long runs to avoid clipping into 75 ohm loads.

MAX9675ECQ+ - 16x16 110MHz Video Crosspoint Switch | Analog Devices

The Analog Devices (formerly Maxim Integrated) MAX9675ECQ+ is a 110MHz, 16x16 non-blocking video crosspoint switch with programmable gain, housed in a 100-pin TQFP (14x14 mm) package. It integrates 16 buffered inputs and 16 buffered outputs, allowing any input to be routed to any output (or to multiple outputs simultaneously) without external buffering. The device operates from a single 2.7V to 5.5V supply and supports -40C to +85C ambient operation. A crosspoint switch is a configurable analog/digital routing element used to connect any of N inputs to any of M outputs under serial or parallel control. Within a video distribution or matrix-switching system hierarchy, the MAX9675 sits between upstream source buffers (DACs, decoders, equalizers) and downstream line drivers or displays. It belongs to the broader family of video switches and signal-routing ICs, providing point-to-point flexibility that discrete FET matrices cannot match in density or bandwidth. The device is fabricated in Maxim's BiCMOS process, which combines bipolar drive capability with CMOS logic density. The MAX9675ECQ+ delivers 110MHz -3dB bandwidth and supports programmable gain per output, allowing cable-loss compensation and signal-level standardization across heterogeneous displays. Its serial programming interface simplifies microcontroller hook-up, while the non-blocking architecture guarantees that any input-to-output connection is independent of all others. Matrix-mode programming allows multiple simultaneous routings, suitable for picture-in-picture, video walls, and security surveillance routers. Typical applications include broadcast video routing, security and surveillance matrices, video conferencing systems, automotive infotainment multiplexers, medical imaging displays, and test & measurement video switches. The 100-pin TQFP footprint gives an exposed die for thermal dissipation and easy hand-solder rework during prototype bring-up. When designing with this device, treat each output as a wideband op-amp output - follow with a 75-ohm series termination resistor to drive standard video loads. Use short, impedance-controlled PCB traces (microstrip or stripline, 50-ohm characteristic impedance) and place bypass capacitors as close to the supply pins as possible to preserve the 110MHz bandwidth.

MAX9744ETH+ - 20W Stereo Class D Audio Amp | Maxim Integrated
MAX9744ETH+

MAX9744ETH+ - 20W Stereo Class D Audio Amp | Maxim Integrated

The Maxim Integrated MAX9744ETH+ is a 20W per-channel stereo Class D audio power amplifier housed in a 44-pin TQFN (7x7 mm) exposed-pad package. It combines Class AB audio performance with Class D efficiency, eliminating the need for a bulky heatsink while delivering up to 22.5W output power into 4Ω loads from a single 4.5V to 14V supply. A Class D audio amplifier is a switching amplifier topology that uses high-frequency pulse-width modulation (PWM) to drive the output stage. By keeping its output transistors fully on or fully off, it achieves efficiencies above 90% versus the 50-70% typical of linear Class AB designs. The MAX9744 uses filterless spread-spectrum modulation, meaning the PWM switching frequency is intentionally dithered to spread spectral energy and lower radiated RF emissions from speaker cables, allowing designers to omit the LC output filter normally required by Class D stages. Key features include integrated volume control selectable between I2C digital interface or analog DC control, low 0.04% THD+N, click-and-pop suppression (Depop), thermal-overload protection, short-circuit protection, and a mute function. The device operates from a single 4.5V to 14V supply, supports differential or single-ended inputs, and provides adjustable gain via external resistors. The 44-pin TQFN-EP package exposes a thermal pad that must be soldered to PCB ground for rated power dissipation. The MAX9744's Class D architecture drives a stereo BTL (bridge-tied load) output stage. Each channel delivers up to 20W continuous into 4Ω at 12V VDD with 10% THD+N. Spread-spectrum modulation typically centers around 330kHz with up to ±10% frequency deviation, lowering EMI by 5-10 dB compared to fixed-frequency Class D amplifiers and enabling CISPR 22 / CISPR 25 compliance with simple PCB layout practices. Typical applications include LCD/PDP televisions, all-in-one PCs, multimedia speaker docks, gaming consoles, and automotive head-unit aux amplifiers. The integrated volume control and mute simplify interfaces with system microcontrollers, while the filterless topology reduces BOM count and PCB area versus LC-filtered Class D solutions. When designing with this device, pay attention to PCB layout around the exposed thermal pad: it must be soldered to a large copper pour (>= 1 sq inch) on the top or bottom layer for rated power delivery. Use star-ground topology to isolate the analog ground (AGND) and power ground (PGND) returns, and place the input RC network as close to the IN+/IN- pins as possible.

The Analog Devices MAX98090AEWJ+T is an ultra-low-power stereo audio codec with a 24-bit I2S interface, six configurable input pins, and integrated audio signal processing, packaged in a 49-WLP measuring 3.15 mm by 3.15 mm. The device combines microphone, line, headphone, and speaker signal-path functions in a compact package for portable audio equipment. According to the manufacturer product page, its high-performance, low-power design and flexible input scheme make it suitable for portable applications. An audio codec is an integrated signal-processing semiconductor that converts between digital audio data and analog microphone, line, or headphone signals. The MAX98090 belongs to the broader codec hierarchy: audio codec → mixed-signal interface IC → digital and analog signal conversion → portable audio electronics. Its integrated architecture can reduce the number of external components needed for a compact audio subsystem while supporting configurable analog and digital microphone inputs. The MAX98090 provides a 24-bit audio interface and an I2S-oriented digital audio connection, while its six input pins can be configured for analog or digital microphones, differential or single-ended line inputs, or full-scale differential inputs. The manufacturer identifies the MAX98090 as an ultra-low-power stereo audio codec designed for portable systems. Its WLP package provides a small physical footprint, but the package requires careful PCB layout, exposed-pad thermal management, and assembly controls. Typical signal paths include digital microphones feeding an I2S-compatible processor, analog microphone or line sources feeding the codec inputs, and headphone or speaker-related audio functions. The flexible input configuration allows one codec family to address portable recording, communication, and multimedia designs. The exact input sensitivity, sample-rate limits, headphone-output capability, and speaker-output current should be confirmed from the manufacturer datasheet for the final application. The main design consideration is ensuring that microphone and line inputs are correctly configured, bypassed, and referenced. I2S clocking, digital microphone power sequencing, analog grounding, and WLP assembly must be validated together rather than treated as independent blocks. Use the manufacturer datasheet and recommended application information for the complete pin mapping, electrical limits, and PCB land pattern. This product page synthesizes verified manufacturer descriptions, distributor availability, package information, pricing references, and practical design guidance.

MAX9814ETD+T - Mic Amplifier with AGC | Analog Devices

The Analog Devices MAX9814ETD+T is a low-cost, high-quality microphone amplifier with automatic gain control (AGC) and a low-noise microphone bias generator, housed in a 14-pin TDFN (3x3 mm) surface-mount package. It integrates a low-noise preamplifier, a variable-gain amplifier (VGA), an output amplifier, a microphone bias-voltage generator, and AGC control circuitry in a single IC, and operates from a 2.7V to 5.5V single supply. According to the Maxim datasheet, the device targets portable and consumer audio applications where dynamic range, size, and BOM cost all matter. A microphone preamplifier is the front-end analog stage that boosts a microphone's small output signal to a usable line level before ADC or codec digitization. In the signal-chain hierarchy, it sits between the transducer (electret or MEMS microphone) and the ADC or audio codec. By integrating AGC and bias generation, the MAX9814ETD+T removes two external ICs and several discrete components, simplifying the BOM while keeping the dynamic range high enough for speech and music capture. Key features include a low-noise preamp with selectable gain settings (40 dB, 50 dB, 60 dB), a low-noise 2.5V microphone bias generator with PSRR above 100 dB, integrated AGC with selectable attack/release ratios, a low 3.7 mA supply current, and a <1 uA shutdown mode. The TDFN-14 3x3 mm package gives a small PCB footprint with an exposed thermal pad that must be soldered to the ground plane for rated thermal performance. The architecture chains the low-noise preamp into the VGA, which is driven by an envelope detector that sets the gain based on the output amplitude. The internal bias generator rails the electret capsule cleanly so even budget microphones achieve >100 dB dynamic range. Typical THD+N at 1 kHz is well below 1% at rated output, sufficient for voice and high-quality portable recording. Typical applications include Bluetooth headsets, digital still and video cameras, IP phones and teleconferencing units, portable recorders, PDAs, and karaoke/entertainment systems. The wide 2.7V-5.5V input range covers a single Li-ion cell (3.0V-4.2V) plus USB-powered 5V designs. When laying out the PCB, tie the exposed pad to a solid ground pour for thermal relief and lowest noise. Place the bypass and bias capacitors within a few millimetres of the IC and route microphone traces away from switching converters to preserve SNR.

MAX98357AETE+T - 3.2W PCM Class D Amp | Analog Devices

The Analog Devices (Maxim Integrated) MAX98357AETE+T is a tiny, low-cost, digital pulse-code modulation (PCM) input Class D audio amplifier that delivers industry-leading Class AB audio performance with Class D efficiency, packed in a 16-pin TQFN (3x3 mm) package with exposed pad. What is a Class D amplifier? A Class D audio amplifier is a switching amplifier that modulates the audio input into a high-frequency PWM carrier, then low-pass filters it back to analog at the output. Compared to Class AB amplifiers, Class D designs achieve substantially higher efficiency (often 80-95%), drastically reducing wasted heat and enabling smaller form factors without heatsinks. This makes them dominant in modern portable, IoT, and battery-powered audio applications. Key features include 3.2W output power into a 4 ohm load, 77dB PSRR, and 92% efficiency into 8 ohms. The device supports 2.5V to 5.5V supply operation with only 2.4mA quiescent current, an I2S/left-justified/TDM digital audio interface accepting 35+ clocking schemes, selectable 9dB/12dB/15dB/18dB/21dB gain, and a digital envelope (DE) idle-pin mute for click-and-pop suppression. The filterless architecture eliminates output inductors, saving PCB area and BOM cost. The MAX98357A uses a single-supply rail-to-rail PWM modulator with spread-spectrum modulation and an internal oscillator factory-trimmed for low EMI. Its automatic sample-rate detection (32kHz to 96kHz) eliminates I2C programming, and proprietary edge-rate control permits FCC and CE compliance without expensive filtering on the speaker leads. Typical applications include smart speakers and voice assistants (Amazon Echo, Google Nest Mini), wearable audio devices, portable Bluetooth speakers, single-board computers like the Raspberry Pi, video doorbell chimes, smart appliances, and IoT notification tone generators. For improved performance and lower power consumption, Analog Devices recommends the MAX98360 as a newer-generation alternative. When designing with this part, note that the exposed pad (EP) must be soldered to a continuous ground plane for both electrical reference and thermal dissipation. Because the output is a BTL switching stage, the speaker leads should be routed as a short, tightly-coupled differential pair to minimize EMI loop area. This page synthesizes distributor stock levels, verified alternatives, and practical PCB layout notes not collected in the manufacturer datasheet alone, helping engineers select and source the right PCM Class D amplifier for their audio product.

MAX9867ETJ+

MAX9867ETJ+ - Ultra-Low Power Stereo Audio Codec | Analog Devices

The Analog Devices MAX9867ETJ+ is an ultra-low power stereo audio codec designed for portable consumer devices such as mobile phones, portable gaming consoles, and portable media players. Housed in a 32-pin TQFN (5x5 mm) package, the MAX9867 integrates stereo differential microphone inputs, single-ended line inputs, stereo headphone amplifiers, and a flexible digital audio interface supporting I2S, TDM, and left-justified formats. An audio codec (coder-decoder) is a mixed-signal integrated circuit that performs both ADC (analog-to-digital conversion) for the recording path and DAC (digital-to-analog conversion) for the playback path. Codecs sit at the boundary between the analog acoustic domain and the digital processing domain, and ultra-low-power codecs such as the MAX9867 are specifically engineered for battery-operated portable electronics where standby and active current budgets are critical system design constraints. Key features include 1.8V single-supply operation, 6.7 mW playback power consumption, support for both analog and digital microphones, and comprehensive click-and-pop suppression circuitry. The integrated stereo headphone amplifiers support differential, single-ended, and capacitorless output configurations, delivering up to 10 mW into 32 ohm headphones in capacitorless mode. The device also includes configurable digital filtering, programmable gain, and an I2C-compatible control interface with a full register map for fine-grained audio path tuning. Architecturally, the MAX9867 combines 18-bit ADC and DAC paths with a low-noise analog front end, on-chip microphone bias generation, and integrated PLL for flexible audio clocking. The 32-pin TQFN package with exposed thermal pad enables compact PCB layouts in space-constrained portable designs, while the I2C control interface simplifies integration with host application processors and Bluetooth audio SoCs. Typical applications include mobile phone audio subsystems, portable gaming console audio, portable media player headphone outputs, Bluetooth audio dongles, and wearable audio devices. The 1.8V single-suprail capability makes the MAX9867 directly compatible with modern application-processor PMIC rails common in portable designs. When designing with the MAX9867, ensure that the exposed thermal pad (EP) on the 32-pin TQFN is soldered to a properly sized copper pour for both thermal dissipation and ground reference integrity. The capacitorless headphone output mode eliminates large AC-coupling capacitors on the PCB but requires careful ground-layout practices to avoid channel crosstalk. This page consolidates distributor pricing, drop-in alternatives, and design guidance beyond what is in the MAX9867 datasheet alone, including a curated selection guide and parametric comparison against same-package alternatives.

MAX98740BENL+TG7 - Low-EMI Class D Audio Amplifier IC

The Analog Devices (formerly Maxim Integrated) MAX98740BENL+TG7 is a high-efficiency, low-EMI Class D audio amplifier IC that integrates boost converter functionality in a compact 16-bump WLP package. It delivers up to 2.45W of output power into an 8 ohm load from a single lithium-ion (Li+) battery input, making it well suited for portable mono audio applications. The device combines a filterless Class D output stage with a synchronous-rectification boost converter to maintain output voltage headroom across the full Li+ discharge curve. A Class D audio amplifier (also called a switching amplifier) is a type of power amplifier that uses pulse-width modulation (PWM) at high frequency (typically 250 kHz to 2 MHz) to drive the output stage, achieving efficiencies above 90% compared to 50-65% for traditional Class AB amplifiers. This efficiency gain is critical for battery-powered portable devices where heat dissipation and battery life are primary design constraints. Within the broader component taxonomy, Class D audio amplifiers fall under amplifier ICs (audio) -> amplifier ICs -> integrated circuits -> semiconductors. Key features of the MAX98740BENL+TG7 include integrated click-and-pop suppression, differential input architecture for improved common-mode noise rejection, low total harmonic distortion plus noise (THD+N), and a dedicated shutdown pin for power sequencing. The synchronous boost converter maintains the amplifier supply rail even as the Li+ cell drops from 4.2V to 3.0V, preserving audio output level across the entire discharge cycle. The device operates from a single 2.7V to 5.5V supply, includes thermal and short-circuit protection, and supports I2C-free analog gain control. The WLP-16 (Wafer-Level Package, 1.66 mm x 1.66 mm) footprint makes it appropriate for ultra-compact PCBs found in wearables, hearables, and IoT audio endpoints. The +TG7 suffix indicates tape-and-reel packaging with 7-inch reels. Typical applications include Bluetooth/wireless speakers, smart-home voice assistants, portable gaming audio, wearable fitness devices with audio feedback, and hearing assistance personal sound amplifiers. When designing with the MAX98740BENL+TG7, designers should follow the datasheet reference layout for the WLP land pattern and provide adequate thermal copper under the bumps to manage the WLP junction-to-ambient thermal path.
