GENERAL DESCRIPTION
The TDA8547TS is a two channel audio power amplifier
for an output power of 2 × 0.7 W with a 16 Ω load at a 5 V
supply. At a low supply voltage of 3.3 V an output power of
0.6 W with an 8 Ω load can be obtained. The circuit
contains two BTL amplifiers with a complementary
PNP-NPN output stage and standby/mute logic.
The operating condition of all channels of the device
(standby, mute or on) is externally controlled by the
MODE pin. With the SELECT pin one of the output
channels can be switched in the standby condition. This
feature can be used for loudspeaker selection and also
reduces the quiescent current consumption.
When only one channel is used the maximum output
power is 1.2 W.
