Overview
The LA7953 Audio Controller is a single-chip, liner IC
featuring a built-in expansion circuit. The device also fea-
tures a 4-input 1-output audio switch, an acoustic mute, a
LINE-OUT output, and audio control functions for volume,
balance, bass and treble on-chip.
Excellent audio reproduction can be obtained using the right
channel expansion circuit.
The LA7953 operates on a single 12V power supply and is
available in 30-pin plastic DIPs.
Features
• On-chip audio controller and audio switch facilitate de-
• Audio controller for volume, balance, bass and treble.
• 4-input/1-output audio switch.
• On-chip expansion circuit ensures excellent sound repro-
• LINE-OUT output.
• Acoustic mute.
