4.8.1 Audio Input and Output
The audio input circuitry consists of 2 independent 16-bit high-quality ADC channels:
Programmable as either stereo or dual-monoinputs.
1 input programmable as either microphone or line input,the other as line input only.
Each channel can be connected as either single-ended or fully differential.
Each channel has an analog and digital programmable gain stage.
The audio output circuitry consists of a dual differential class A-B output stage.
Note:FSC-BT1006A is designed for a differential audio output. If a single-ended audio output is required,
use anexternal differential to single-ended converter.
4.8.2 Audio Codec Interface
The interface has the following features:
Stereo and mono analog input for voice band and audio band
Stereo and mono analog output for voice band and audio band
Note:To avoid any confusion regarding stereo operation, this data sheet explicitly states which is the left and
rightchannel for audio output. Regarding audio input, software, and any registers, channel 0 or channel
Arepresents the left channel and channel 1 or channel B represents the right channel.
