DESCRIPTION

Description

OVERVIEW

Product Overview

The ADA4940-1ARZ is a single-channel fully differential amplifier from Analog Devices, commonly used to convert single-ended or differential signals into differential outputs for driving differential-input ADCs. It can serve analog signal chains in data acquisition, instrumentation, and communications, performing buffering, gain setting, and common-mode level adjustment. The fully differential structure helps reduce even-order distortion and improve common-mode rejection. Supply voltage, bandwidth, noise, and power consumption should be based on the original datasheet.

APPLICATIONS

Applications

  • Used for front-end driving of differential-input ADCs.
  • Used for analog signal conditioning in data-acquisition systems.
  • Used for differential signal amplification in industrial instrumentation.
  • Used for IF signal processing in communication equipment.
FEATURES AND BENEFITS

Features and Benefits

  • Fully differential output helps suppress common-mode noise.
  • Single-channel structure suits multi-channel parallel designs.
  • Targets ADC driving to simplify signal-chain design.
  • Electrical parameters must be confirmed from the original datasheet.
ADDITIONAL DETAILS

Additional Details

Before ordering, verify the package, temperature grade, and orderable suffix to confirm suitability for the target application. Obtain the original datasheet to check parameters, as batch and packing differences may exist.

Verify product details against the manufacturer datasheet before purchase.
