TDA8547 - 2 x 0.7W BTL AUDIO AMPLIFIER
The UTC TDA8547 is a two channel audio power amplifier for an output power of 2 × 0.7W with a 16Ω load at a 5V supply.
At a low supply voltage of 3.3V an output power of 0.6W with an 8Ω load can be obtained.
The circuit contains two BTL amplifiers with a complementary PNP-NPN output stage and standb
