This evaluation module (EVM) features a low-power stereo audio ADC with several analog inputs, digital output, audio routing, mixing, and digital filter capabilities. A complete circuit description, schematic diagram, and bill of materials are also included. Note that the TLV320ADC3101 uses the I 2 C ™ bus for register control. Any reference to the SPI control bus in this document is due to the presence of this interface on the USB-MODEVM motherboard.
