1.1 Introduction

The PCM1841-Q1EVM is an evaluation module (EVM) designed to demonstrate the performance and functionality of the PCM1841-Q1 device. The PCM1841-Q1 is a high-performance audio analog-to-digital converter (ADC) that is configured through logic-level mode selection pins and does not require a digital interface such as I2C or SPI to configure registers. As such, no software is necessary to interface with the EVM. The EVM is powered with a single 5V supply. Access to the converter output is provided on the audio serial interface in I2S, LJ, or TDM format.

This user's guide describes the function and use of the PCM1841Q1EVM. This document includes the hardware configuration instructions, a quick-start guide, jumper and connector descriptions, schematics, and printed-circuit board (PCB) layout that demonstrate TI's recommended practices for these devices.
