EVM WARNINGS AND RESTRICTIONS

It is important to operate this EVM within the input voltage range of 1.8 VDC to 5 VDC and the output voltage range of 0 VDC and 5 VDC.

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 30°C. The EVM is designed to operate properly with certain components above 85°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.

1.2 Introduction

The Modular MSOP8 Evaluation Module is an updated version of the Burr-BrownDEM-MSOP8evaluation board. The EVM is designed so that a single printed wiring board (PWB) supports a variety of high speed 12 and 16 bit serial ADC’s.

The modular EVM form factor allows for direct evaluation of the ADC’s performance and operating characteristics. This EVM is compatible with the 5-6KInterface Board (SLAU104) from Texas Instruments and additional 3rd party boards such as the HPA449 demonstration board from SoftBaugh, Inc. (www.softbaugh.com) and the Speedy33t from Hyperception, Inc. (www.hyperception.com).
