Overview Features
Monolithic Linear IC
4CH Bridge (BTL) Driver for CD
The LA6563 is a 4CH bridge (BTL) driver for CD players.
* Built-in bridge connection (BTL) POWER AMP 4CH * IO max 1A * MUTE circuit (main power is ON/OFF) with 3 systems * Built-in STBY circuit (all circuits are OFF) * Provides bias voltage (VREF) switching function (Select external or internal reference voltage. Internal reference voltage is 2.5V: TYP.) * Output voltage (dynamic range) is high. (6V: TYP)

*1. Voltage for both ends of the load when connecting the 8 load between outputs. Input is H or L. Output is saturated. *2. Input AMP is 0 dB for BUFFER. *3. Design guaranteed performance. *4. MUTE is HI for output ON and LOW for output OFF (AMP output is OFF, HI impedance). Each MUTE activates independently to a corresponding channel. *5. VREF-SW is set to "H" for switching to external reference voltage and "L" for switching to internal reference voltage.
