The TDA8943SF is a mono BTL audio power amplifier capable of delivering 6 W
output power to an 8
external heatsink. The voltage gain is fixed at 32 dB.
With the three-level MODE input the device can be switched from 'standby' to 'mute'
and to 'operating' mode.
The TDA8943SF outputs are protected by an internal thermal shutdown protection
mechanism and a short-circuit protection.
