Ordering number : EN7777A
LA6572
Monolithic Linear IC
5-CH Driver for Mini Disc and
Compact Disk Applications (BTL : 5CH)
Overview
The LA6572 power amplifier 5-channel (BTL) built-in.
Features
• Power amplifier 5-channel (BTL) built-in.
• IO 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.
