Monolithic Linear IC

For CD Players and Recorders

LA6548NH

Four-Channel Driver IC

Overview

The LA6548NH is a four-channel driver IC for CD players and recorders (four BTL amplifier channels).

Functions

• Four BTL connection power amplifier channels

• I max 0.7A

• Built-in level shifters

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

(This circuit applies to the BTL amplifier circuits. It does not control operation of the regulator.)

• Built-in regulator (provides a 3.3V output using an external pnp transistor)

• Thermal protection circuit (thermal shutdown circuit)
