DESCRIPTION

Description

OVERVIEW

Product Overview

The ADA4945-1ACPZ is a single-channel fully differential amplifier from Analog Devices, intended for analog signal chains that require differential signal conditioning and ADC driving. It converts single-ended or differential inputs into differential outputs, providing buffering, gain, and common-mode level adjustment ahead of analog-to-digital conversion. Its fully differential architecture helps suppress even-order harmonics and common-mode interference, making it suitable for precision data-acquisition front ends. Supply voltage, bandwidth, noise, and power consumption should be confirmed from the original datasheet.

APPLICATIONS

Applications

  • Used as a front-end driver and signal conditioner for differential-input ADCs.
  • Used for analog signal buffering in precision data-acquisition systems.
  • Used for differential amplification of IF signals in communication receivers.
  • Used for differential signal transmission in industrial instrumentation.
FEATURES AND BENEFITS

Features and Benefits

  • Fully differential output structure helps suppress common-mode interference.
  • Single-channel design allows flexible layout in multi-channel systems.
  • Supports differential signal conditioning for ADC driving requirements.
  • Gain, bandwidth, and power figures must be confirmed from the original datasheet.
ADDITIONAL DETAILS

Additional Details

When purchasing, verify the package type, orderable part-number suffix, and packing method, and confirm the operating temperature grade. Batch-to-batch differences may exist; obtaining the original datasheet and material specification for comparison is recommended, with electrical parameters subject to the original documentation.

Verify product details against the manufacturer datasheet before purchase.
