MAX4402ASA-T

Instrumentation, Op Amps, Buffer Amps Overview

The MAX4402ASA+T is a dual, general-purpose operational amplifier manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +2.5V to +5.5V supply and features rail-to-rail output voltage swing. The device draws 320µA of quiescent current per amplifier and delivers ±1.4mA of output current. It is unity-gain stable with an 800kHz gain-bandwidth product and can drive capacitive loads up to 400pF. The component is specified for operation over a temperature range of -40°C to +125°C and is housed in an 8-pin SOIC package.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Rail-to-rail output stage capable of swinging within millivolts of the supply rails while driving a 2kΩ load
• Unity-gain stability maintained for capacitive loads up to 400pF without external compensation
• Ground-sensing inputs allowing common-mode voltage range to extend down to the negative supply rail
• Low quiescent current consumption optimized for portable and battery-powered applications

Instrumentation, Op Amps, Buffer Amps Applications

• Single-supply zero-crossing detectors
• Infrared receiver signal processing
• Sensor signal detection circuits
• Electronic ignition modules
• Portable communications equipment

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify that the ordering suffix corresponds to the specific package type required, as the MAX4402 family includes SOT23-8, µMAX, and SOIC variants. Confirm RoHS compliance status via the manufacturer's documentation. Ensure the design accounts for the absence of a shutdown pin on this specific dual amplifier variant, unlike the MAX4401 single-channel model.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select the MAX4402ASA+T when a dual-channel solution is needed with rail-to-rail output capabilities under a single low-voltage supply. This part is suitable for designs requiring ground-sensing inputs and moderate bandwidth. Note that the shutdown feature is exclusive to the MAX4401; if power-down functionality is required, consider alternative models within the series.

Instrumentation, Op Amps, Buffer Amps Part Context

This component belongs to the MAX4400–MAX4403 family of low-cost, single-supply op amps. While the MAX4400 is a single channel and the MAX4403 is a quad, the MAX4402 provides two amplifiers in one package. All devices share similar electrical characteristics, including low power consumption and high open-loop gain, but differ in channel count and available packages.
