Description

The TIDA-01052 reference design aims to highlight system performance increases seen using a negative voltage rail on the analog front end driver amplifiers rather than ground. This concept is relative to all analog front ends, however this design is aimed specifically at automatic test equipment.

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
