Abstract

The TLV320ADCx140/PCMx140-Q1 device family (TLV320ADC3140, TLV320ADC5140, and TLV320ADC6140) is a quad-channel, high-performance, analog-to-digital converter (ADC) for audio applications. The TLV320ADCx120 family (TLV320ADC3120, TLV320ADC5120, and TLV320ADC6120) is as smaller dual-channel, high-performance, ADC for audio application. The PCMx120-Q1 Family (PCM3120-Q1,PCM5120-Q1,PCM6120-Q1 is automotive grade dual channel high performance ADC for audio application This document describes how to configure multiple TLV320ADCx140/PCMx140-Q1 and/or TLV320ADCx120/PCMX120-Q1 devices to share a single TDM and I2C Bus.
