Monolithic Linear IC

5-CH Driver for Mini Disc and

Compact Disk Applications (BTL : 5CH)

LA6572

Overview

The LA6572 power amplifier 5-channel (BTL) built-in.

Features

• Power amplifier 5-channel (BTL) built-in.

• I max 1A.

• Level shift circuit built-in.

• Three channels (2-1-1) of MUTE circuit (output ON/OFF) incorporated. Only CH5 normally ON.

(Operative independently for each of MUTE1: CH1, 2, MUTE2: CH3, MUTE3: CH4. Inoperative for 3.3REG).

• 3.3V power supply (3.3VREG) incorporated (PNP transistor connected externally).

• With 3.3V power supply (3.3VREG) ON/OFF function (EN-REG)

(Operative for 3.3VREG only (inoperative for BTL AMP).

(3.3VREG: OFF with EN-REG: L, 3.3VREG: ON with EN-REG : H).

• Operative for the fixed internal VREF (1.65V: TYP) for 5CH only.

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