MAX9880A Evaluation Kit
General Description
The MAX9880A evaluation kit (EV kit) is a fully assem-
bled and tested surface-mount PCB that evaluates the
MAX9880A IC, which is a low-power, high-performance,
stereo audio codec with audio processing. To facilitate
evaluation, the EV kit includes input and output RCA
connections, capless and single-ended headphone con-
nectors (J3, J4), and two on-board digital microphones
(U15, U16).
Integrated into the EV kit design is a digital audio trans-
ceiver (U11) and a USB stereo audio DAC (U12). The
digital audio transceiver provides audio input and output
through the on-board TOSLINK connectors (J5, J6)
and the USB stereo audio DAC provides audio input
through the mini-USB connector (J10).
The device’s I 2 C/2-wire and SPI K control bus are inter-
