TDA8551 Audio Ampllifier 1 x 1 W

TDA8551general 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.
TDA8551 features:
One pin digital volume controlVolume setting with UP/DOWN pulsesFlexibility in useFew external componentsLow saturation voltage of output stageStandby mode controlled by CMOS compatible levelsLow standby currentNo switch-on/switch-off plopsHigh supply voltage ripple rejectionProtected against electrostatic dischargeOutputs short circuit safe to ground, VP and across the loadThermally protected.
