EVM WARNINGS AND RESTRICTIONS

It is important to operate this EVM within the input voltage range of±6 V and the output voltage

range of 0 V and 5.5 V.

Exceeding the specified input range may cause unexpected operation and/or irreversible

damage to the EVM. If there are questions concerning the input range, please contact a TI

field representative prior to connecting the input power.

Applying loads outside of the specified output range may result in unintended operation and/or

possible permanent damage to the EVM. Please consult the EVM User’s Guide prior to

connecting any load to the EVM output. If there is uncertainty as to the load specification,

please contact a TI field representative.

During normal operation, some circuit components may have case temperatures greater than

60°C. The EVM is designed to operate properly with certain components above 60°C as long

as the input and output ranges are maintained. These components include but are not limited

to linear regulators, switching transistors, pass transistors, and current sense resistors. These

types of devices can be identified using the EVM schematic located in the EVM User’s Guide.

When placing measurement probes near these devices during operation, please be aware

that these devices may be very warm to the touch.

1.1 Features

-Full-featured evaluation board for the high-speed ADS8402 (1.25 MSPS)

and the ADS8412 (2 MSPS) high speed, 16-bit, single channel, parallel

interface SAR-type analog-to-digital converters.

-Onboard signal conditioning

-Onboard reference

-Input and output digital buffer

-Onboard decoding for stacking multiple EVMs

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.
