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.
APPLICATIONS
Portable consumer products
Personal computers
Telephony.
