Overview

The LA6559 is a 5-channel driver (BTL : 4-channel, H bridge : 1-channel) for CD players.

Functions

• 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 MUTE1 : CH1 and MUTE2 : CH2 to 4 and not operable for the H bridge of 3.3VREG)

• 3.3V regulator built-in (external PNP transistor).

• With a function to set the loading output voltage

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