Features
1) Contains the input amplifier, wind noise deletion fil-
ter, ALC, 30kHz LPF, line amplifier, stereo head-
phone amplifier, and BTL monaural speaker amplifi-
er required to configure a analog signal I / O inter-
face (audio I / O) all on one chip.
2) With the internal 3-line serial control decoder circuit,
serial control enables the setting of the various
modes for the IC.
