NXP Semiconductors TDA8552T
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. The headphone sense input (HPS) can be used to detect if a headphone is plugged into the jack connector.| Part No. | TDA8552T |

DESCRIPTION
TDA8552T; TDA8552TSGENERAL DESCRIPTION
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. Using the selection pin (GAINSEL) the maximum gain can be set at 20 or 30 dB.
