Monolithic Linear IC
LA6525M
Four-Channel Bridge Driver for Compact Disc Players
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 22k resistor. 2. Output-to-ground voltage when an 8 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 100k resistor, inverting input is connected to output through a 100k resistor. The current is determined from the voltage across the resistors. Pd max - Ta

Sample Application Circuit
Specifications of any and all SANYO products described or contained herein stipulate the performance, characteristics, and functions of the described products in the independent state, and are not guarantees of the performance, characteristics, and functions of the described products as mounted in the customer's products or equipment. To verify symptoms and states that cannot be evaluated in an independent device, the customer should always evaluate and test devices mounted in the customer's products or equipment. SANYO Electric Co., Ltd. strives to supply high-quality high-reliability products. However, any and all semiconductor products fail with some probability. It is possible that these probabilistic failures could give rise to accidents or events that could endanger human lives, that could give rise to smoke or fire, or that could cause damage to other property. When designing equipment, adopt safety measures so that these kinds of accidents or events cannot occur. Such measures include but are not limited to protective circuits and error prevention circuits for safe design, redundant design, and structural design. In the event that any or all SANYO products(including technical data,services) described or contained herein are controlled under any of applicable local export control laws and regulations, such products must not be expor ted without obtaining the expor t license from the authorities concerned in accordance with the above law.
