Analog Interface

2 Analog Interface

For maximum flexibility, the TSC2017EVM 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 TSC. Consult Samtec at www.samtec.com, or call 1-800-SAMTEC-9 for a variety of mating connector

options. Table 1 summarizes the pinouts for the analog interface pinout J1.
