LA6571

Overview

The LA6571 is 5-channel driver for mini disk and compact disk applications (BTL-AMP: 5CH).

Features

• Power amplifier 5-channel built-in.

• IO max 1A

• Level shift circuit built-in.

• Mute circuit (output ON/OFF) with three built-in channels (2-2-1).

(Operates independently for each of MUTE1: CH1 and 2, MUTE2: CH3 and 4, and MUTE3: CH5.

Not operating for the regulator (REG))

• Regulator (REG) built-in (external PNP transistor).

Voltage setting (typ: 1.5V or more) with an external resistor

• Overheat protection circuit (thermal shutdown) built-in.
