Analog Interface
For maximum flexibility, the Modular MSOP8 EVM is designed for easy
interfacing to multiple analog sources. Samtec part numbers
SSW-110-22-F-D-VS-K and TSM-110-01-T-DV-P provide a convenient 10-pin
dual row header/socket combination at J1. This header/socket provides
access to the analog input pins of the ADC. Consult Samtec at
www.samtec.com or call 1- 800 - SAMTEC - 9 for a variety of mating connector
options.
