I
Overview
The AN2905FHQ is a sound input/output interface IC
which is optimum for incorporation of sound functions in
a digital still camera. The sound pre-processing prior to the
digital processing and sound post-processing after DAC
are integrated on a single chip. This IC is effective to make
the equipment compact.

Features
Functions required for the sound pre- and post-processings
are integrated on a single chip
The built-in microphone amp. and microphone power
supply
A built-in 0.5 W BTL amp.
Built-in SP power save and electronic volume func-
tions
A beep circuit with electronic volume
A built-in internal microphone amp. on/off function
A built-in AGC switch
A built-in AGC to a speaker amp.
(Prevents the sound distortion, trembling sound and wire
breakdown of the speaker at excessively high voltage
signal input)
