1.2 Introduction

The ADS8402EVM and ADS8412EVM is a modular or stand alone EVM. It has the bare minimum circuitry to showcase the device under test and plug into prototype systems. The onboard decoding circuitry enables the user flexibility to map the A/D to different addresses in processor memory. The power, analog and digital control lines are on standard 0.1-in. header/socket connectors, at the edges of the PWB, making it easy to wire into prototype systems for evaluation. The EVM has been designed for direct evaluation of the analog-to-digital converter performance and operating characteristics. This EVM is compatible with the 5- 6K interface board (SLAU104) from Texas Instruments and additional third party boards.
