1 Introduction

TAC5412-Q1 is a CODEC with dual-channel analog-to-digital converters whose input pins (IN1P/M and IN2P/M) are configurable as differential inputs, single-ended inputs or single-ended mux inputs in AC or DC coupling. The type of input is configured through ADC_CH1_INSRC and the AC or DC coupling mode is configured through ADC_CH1_CM_TOL [00] or ADC_CH1_CM_TOL [01].
