Overview

The LA6576 is a 5-channel driver for optical disc drives with a VREF switching function.

Features

• Power amplifier 5-channel built-in. (Bridge-connection (BTL): 4-channel, H bridge: 1-channel)

• IO max 1A.

• Level shift circuit built-in (except H bridge).

• Mute circuit (output ON/OFF) built-in. (Operable with BTL AMP with CH1 to 4 and not operable for the H bridge of 5VREG)

• 5V regulator built-in (external PNP transistor).

• With VREF changeover function (H: external, L: internal).

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