1. Product description
This device is one channel 16-bit ADC with USB I/F for monaural microphone, and operates as IN
device.
2. Descriptor structure
This device includes one configuration, two interfaces, which are an audio control interface (0) and
an audio streaming interface (1), two endpoints, which are endpoint 0 for default pipe, and endpoint
1 for audio streaming.
The descriptor is partly fixed and partly programmable by means of selectable test pin map. The
programmable descriptors are marked with a star.
