Overview
The LA6525M is a four-channel, high-current bridge driver
IC with output muting. It features two dual-output 400mA
(max) and two dual-output 700mA (max) channels, making it ideal for use in compact disc players.
The LA6525M incorporates a reference voltage switch, a
thermal protection circuit and two input buffer amplifiers
in addition to the output driver amplifiers.
The LA6525M operates from a 5V supply and is available
in 30-pin MFPs.

Notes
1. Amplifier non-inverting inputs are held at 0.5V and amplifier inverting inputs are connected to outputs through a 22kΩ
resistor.
2. Output-to-ground voltage when an 8Ω load is connected between a pair of bridge amplifier outputs.
3. Voltage differential between a pair of bridge amplifier outputs.
4. Amplifier non-inverting input is connected to 0.5VCC through a 100kΩ resistor, inverting input is connected to output
through a 100kΩ resistor. The current is determined from the voltage across the resistors.
