FEATURES: One pin digital volume control Volume setting with UP/DOWN pulses Flexibility in use Few external components Low saturation voltage of output stage Standby mode controlled by CMOS compatible levels Low standby current No switch-on/switch-off plops High supply voltage ripple rejection Protected against electrostatic discharge Outputs short circuit safe to ground, VP and across the  load Thermally protected. 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.
