• Four bridge-connected (BTL) power amplifier circuits

• I O max: 1A

• Built-in level shifter circuits

• Muting circuit (on/off control for all outputs)

• High output voltage (dynamic range): 6.5V (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.

• Built-in overheat protection (Thermal shutdown) circuit (Design guarantee)

The LA6242H is a 4-channel motor driver IC for home and car CD players. It provides a pin for switching the channel 1

input.
