Any and all SANYO products described or contained herein do not have specifications that can handle
applications that require extremely high levels of reliability, such as life-support systems, aircraft’s
control systems, or other applications whose failure can be reasonably expected to result in serious
physical and/or material damage. Consult with your SANYO representative nearest you before using
any SANYO products described or contained herein in such applications.
SANYO assumes no responsibility for equipment failures that result from using products at values that
exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges,or other
parameters) listed in products specifications of any and all SANYO products described or contained

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.
