8. Functional description
The TDA8943SF is a mono BTL audio power ampliï¬er capable of delivering 6 W
output power to an 8 ⦠load at THD = 10%, using a 12 V power supply and an
external heatsink. The voltage gain is ï¬xed at 32 dB.
With the three-level MODE input the device can be switched from âstandbyâ to âmuteâ
and to âoperatingâ mode.
The TDA8943SF outputs are protected by an internal thermal shutdown protection
mechanism and a short-circuit protection.
