TDA7297
Brand: STMicroelectronics
TDA7297 is a dual bridge audio amplifier from STMicroelectronics designed for TV and portable radio applications, delivering 15 W + 15 W output power into 8 Ω loads with minimal external components. The device features wide 6 V to 18 V single-supply operation with internally fixed gain, eliminating the need for bootstrap capacitors, Boucherot cells, and SVR capacitors. Integrated stand-by and mute functions, short-circuit protection, and thermal overload shutdown ensure robust and reliable operation in consumer audio systems. It is housed in a 15-pin Multiwatt through-hole power package rated for 0 °C to +70 °C operation.
