A.2 Digital Interface Connectors, P12/J12 and P22/J22

The TLV320DAC3203EVM easily interfaces with multiple control platforms. 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 P12/J12 and P22/J22. These headers/sockets provide access to the digital control and

serial data pins of the device. Consult Samtec at www.samtec.com or call 1-800- SAMTEC-9 for a variety

of mating connector options. Table 5 summarizes the digital interface pinout for the

TLV320DAC3203EVM.
