TIDA-00822

Design files

Overview

This reference design discusses the use and performance of the Digital Variable-Gain high-speed amplifier, the LMH6401, to drive the high-speed analog-to-digital converter (ADC), the ADS54J60 device. Different options for common-mode voltages, power supplies, and interfaces are discussed and measued, including AC-coupling and DC-coupling, to meet the requirements of a variety of applications.

Features

  • Low noise Variable Gain Amplifier
  • Dual High Speed ADC
  • AC and DC coupling
  • Complete clocking solution
  • Tested Reference design that includes an evaluation board, configuration software, and User's Guide
