TDA8551 Datasheet PDF - Philips

GENERAL DESCRIPTION

●The TDA8551; TDA8551T is a one channel 1 W Bridge-Tied Load (BTL) audio power amplifier capable of delivering 1 W output power to an 8 Ω load at THD = 10% using a 5 V power supply. The circuit contains a BTL power amplifier, a digital volume control and standby/mute logic. The TDA8551T comes in an 8 pin SO package and the TDA8551 in a 8 pin DIP package.
