Texas Instruments TLV320AIC31 Evaluation Module (EVM) and USB motherboard TLV320AIC31EVM-PDK TLV320AIC31EVM-PDK 데이터 시트

For maximum flexibility, the TLV320AIC31EVM 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 and J2. These headers/sockets provide access to the analog input
and output pins of the device. Consult Samtec at

or call 1-800-SAMTEC-9 for a variety

of mating connector options.
