MAX4329ESD+

Instrumentation, Op Amps, Buffer Amps Overview

The MAX4329ESD+ is a quad, low-power, rail-to-rail input/output operational amplifier manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single supply of 2.4V to 6.5V or dual supplies of ±1.2V to ±3.25V. Key electrical parameters include a 5MHz gain-bandwidth product, 2V/µs slew rate, and 650µA quiescent current per amplifier. The device features unity-gain stability for capacitive loads up to 500pF, no phase reversal for overdriven inputs, and can drive 250Ω loads. Input offset voltage is typically 700µV, with an operating temperature range of -40°C to +85°C.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Rail-to-Rail operation at both inputs and outputs for low-voltage single-supply compatibility
• Unity-gain stable with high tolerance for capacitive loads up to 500pF
• No phase reversal occurs when inputs are overdriven beyond the supply rails
• Low quiescent current consumption of 650µA per amplifier channel

Instrumentation, Op Amps, Buffer Amps Applications

• Battery-powered data-acquisition instruments
• RSSI systems signal conditioning
• PA biasing in portable equipment
• Low-power, low-voltage applications

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the component status as obsolete before procurement planning. Confirm the package type is 14-SOIC and the temperature grade is E (-40°C to +85°C). Ensure the ordering suffix matches the required tape-and-reel or tube configuration if applicable, though standard availability may be limited due to lifecycle status.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for precision, low-voltage data-acquisition systems requiring rail-to-rail I/O performance. It is suitable where low power consumption and wide bandwidth are critical. Note that unlike the MAX4323/MAX4327 variants, the MAX4329 does not feature a shutdown mode, maintaining constant active current draw.

Instrumentation, Op Amps, Buffer Amps Part Context

The MAX4329ESD+ belongs to the MAX4322/MAX4323/MAX4326/MAX4327/MAX4329 family of single/dual/quad op amps. This series combines wide bandwidth with excellent DC accuracy. While other members like the MAX4323 offer UCSP packaging and shutdown modes, the MAX4329 specifically provides a quad-channel solution in a 14-pin SOIC package without shutdown functionality.
