Functional description
The SA58631 is a single channel BTL audio amplifier capable of delivering 3 W output
power to an 8
load at THD + N = 10 % using a 9 V power supply. Using the MODE pin,
the device can be switched to standby and mute condition. The device is protected by an
internal thermal shutdown protection mechanism. The gain can be set within a range of
6 dB to 30 dB by external feedback resistors.
8.1 Power amplifier
The power amplifier is a Bridge Tied Load (BTL) amplifier with a complementary
PNP-NPN output stage. The voltage loss on the positive supply line is the saturation
voltage of a PNP power transistor, on the negative side the saturation voltage of an NPN
power transistor. The total voltage loss is < 1 V. With a supply voltage of 9 V and an 8
loudspeaker, an output power of 3 W can be delivered to the load.
