MPQ7795 Description
The MPQ7795 is an automotive-grade, low-EMI, differential analog input Class-D audio amplifier with I2C diagnostics. The device is a fully integrated audio amplifier that can drive a mono speaker in a bridge-tied load (BTL) configuration, and it significantly reduces the solution size. The MPQ7795 utilizes a BTL structure capable of delivering 24.5W into 4Ω speakers with a 14.4V power supply (PVDD).
