This is a four-channel audio power amplifier with a 25-watt output. The TDF8541 and TDF8544 are quad Class-AB amplifiers that are controlled via the I2C bus. The TDF8541 and TDF8544 have an asymmetrical or “single-ended” input configuration that produces 25 to 28 W of output power. They operate over a wide voltage range and reduce dissipation and are available in configurations with the Best Efficiency mode. This audio amplification device These advanced Class-AB amplifiers are designed for use in stop/start cars and support listening to audio streams while the car’s internal power supply is down for engine start. They have a voltage range of 6 to 18 volts.
