Abstract

This application note describes the operation of the TAx5x1x/TAx5x1x-Q1 devices in Incremental ADC (IADC) mode. This can be used to digitize slow moving or DC signals with averaging for applications such as sensing. This application note is relevant for the following devices:

  • TAC5212, TAC5112

  • TAA5212

  • TAC5212-Q1, TAC5112-Q1
