TIDA-01050

Design files

Overview

The TIDA-01050 reference design aims to improve the integration, power consumption, performance, and clocking issues typically associated with automatic test equipment. This design is applicable to any ATE system but most applicable to systems requiring a large number of input channels.

Features
  • Negative rail input (NRI), rail-to-rail output (RRO)
  • Wide output common-mode control range
  • Low power consumption
  • High THD, SNR and ENOB
  • Dual supply on AFE maximizing system performance

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
