Appendix A EVM Connector Descriptions
A.1 Analog Interface Connectors
A.1.1 Block B Analog Dual Row Header Details (J13 and J14)
Appendix A
This appendix contains the connection details for each of the main header connectors on the EVM.
For maximum flexibility, the TLV320AIC34EVM 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 J13 and J14. These headers/sockets provide access to the analog input
and output pins of the device. Consult Samtec at www.samtec.com or call 1-800-SAMTEC-9 for a variety
of mating connector options. Table A-1 summarizes the analog interface pinout for the
TLV320AIC34EVM..
