1 Introduction

The PCM1840EVM is an evaluation module (EVM) designed to demonstrate the performance and functionality of the PCM1840 device. The PCM1840 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 5-V supply. Access to the converter output is provided on the audio serial interface in I2S, LJ, or TDM format.
