Analog signal I / O interface for
portable audio applications
BH7760KV
The BH7760KV contains the complete audio I / O analog block on a single-chip IC. Therefore, all necessary func-
tions for a DVC audio analog I / O interface are provided on one chip.
Applications
Portable audio applications
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.
