Overview
The LA8522M is an I/O switching audio signal-processing
IC for use in facsimile units and telephones. It integrates a
crosspoint switch, a BTL power amplifier, an electronic
volume control, a microphone amplifier, and other
functions on a single chip.
Applications
Personal facsimile units and telephones
Functions
Crosspoint switch (equivalent to an 4 × 4 switch)
BTL power amplifier
Electronic volume control
Output level switching (ATT1: 0, –4, –8, –12 dB,
ATT2: 0, –6 dB)
Serial interface
Features
Built-in BTL power amplifier (8 to 32 Ω load): VCC =
5 V, RL = 16 Ω, Pomax = 250 mW
Built-in electronic volume (seven 4.0 dB steps)
Two output level switching circuits (4 positions and 2
positions)
Crosspoint switch that supports mixing
