DATA SHEET
LA6242H Monolithic Linear IC
Four-Channel Bridge Driver
for CD Player
Overview
The LA6242H is a four-channel motor driver IC for home and car CD players. It provides a pin for switching the
channel 1 input.
Functions and Features
• Four bridge-connected (BTL) power amplifier circuits
• IO max: 1 A
• Built-in level shifter circuits
• Muting circuit (on/off control for all outputs)
• High output voltage (dynamic range): 6.5 V (typical, channel 1 only)
• Built-in input operational amplifier (channel 1 only)
• Channel 1 input operational amplifier switching function
• Built-in regulator that uses an external PNP transistor and is set by the value of an external resistor.
