The TDA8552T is a two channel audio power amplifier that provides an output power of 2 × 1.4 W into an 8 Ω load using a 5 V power supply. The circuit contains two BTL power amplifiers, two digital volume controls and standby/mute logic. Volume and balance of the amplifiers are controlled using two digital input pins which can be driven by simple push-buttons or by a microcontroller. 2 x 1.4 W BTL audio amplifiers TDA8552T, TDA8552TS Datasheet: Download
