MAX4402ASA

Instrumentation, Op Amps, Buffer Amps Overview

The MAX4402ASA is a dual, low-cost, general-purpose operational amplifier manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +2.5V to +5.5V supply and draws 320µA of quiescent current per amplifier. The device features rail-to-rail outputs, delivering ±1.4mA of output current, and is unity-gain stable with an 800kHz gain-bandwidth product while driving capacitive loads up to 400pF. It includes ground-sensing inputs and functions within a temperature range of -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific package code suffix against official documentation to confirm physical dimensions and pinout compatibility. Ensure that the operating environment remains within the specified -40°C to +125°C temperature range for guaranteed performance. Confirm power supply constraints strictly adhere to the +2.5V to +5.5V limits to prevent device damage or specification drift.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a dual-channel solution with rail-to-rail output is required under a single supply voltage. It is suitable for applications demanding low quiescent current and high input impedance. Consider alternative models if shutdown mode control or automotive qualification is necessary, as these features are not present in the standard MAX4402 configuration.

Instrumentation, Op Amps, Buffer Amps Part Context

The MAX4402ASA belongs to the MAX4400–MAX4403 family of low-cost, single-supply operational amplifiers. This series provides general-purpose amplification with space-saving packaging options. The MAX4402 specifically offers two independent amplifier channels within an 8-pin SO package, designed for cost-sensitive and space-constrained electronic designs.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Consult official manufacturer substitution guides for verified alternatives. Cross-referencing requires matching channel count, supply voltage range, and package footprint.
