LA8520M

Audio Signal-Processing IC with I/O Switching

system: seven 4-dB steps, receiver amplifier system: two

3-dB steps)

• Low switching noise, low crosstalk characteristics

(crosspoint switch)

Overview

The LA8520M 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.
