LA8520M
Audio Signal-Processing IC with I/O Switching
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.
Applications
Personal facsimile units and telephones
Functions
• Crosspoint switch (equivalent to an 8 × 8 switch)
• BTL power amplifier
• Electronic volume control
• Serial interface
system: seven 4-dB steps, receiver amplifier system: two
3-dB steps)
• Low switching noise, low crosstalk characteristics
(crosspoint switch)
