The TDA8581(T) from Philips
Semiconductors is a 1-watt
Bridge Tied Load (BTL) audio
power amplifier capable of delivering
1 watt output power into an
8-Ω load at THD (total harmonic
distortion) of 10% and using a 5-
V power supply. The schematic
shown here combines the functional
diagram of the TDA8551
with its typical application circuit.
