Abstract

The TLV320ADCx120 (TLV320ADC3120, TLV320ADC5120, and TLV320ADC6120) and PCMx120-Q1 (PCM3120-Q1, PCM5120-Q1, and PCM6120-Q1) family of devices are dual-channel, high-performance, analog-to-digital converters for audio applications. This family of devices supports highly configurable inputs to allow the device to achieve high performance even in the presence of large common-mode signals.

This application note describes the performance of the TLV320ADCx120 and PCMx120-Q1 devices when operating in high common-mode rejection ratio (CMRR) modes for applications with high common-mode requirements.
