Multi-Rail Power Reference Design for Eliminating EMI Effects in High Performance DAQ Systems

Overview

TopologyOther Topology
IC revisionE1

Description

The TIDA-01054 reference design helps eliminate the performance degrading effects of EMI on Data Acquisition (DAQ) systems greater than 16 bits with the help of the LM53635 buck converter. The buck converter enables the designer to place power solutions close to the signal path without the unwanted noise degradation of EMI while saving board space. This design allows for a system SNR performance of 100.13 dB using a 20-bit, 1-MSPS SAR ADC, which almost matches the 100.14 dB SNR performances when using external power sources.
