4、Function Introduction to IC
(1)function introduction to TFA9843J
1)Description
The TFA9843J contains two identical audio power amplifiers. The TFA9843J can be
used as two Single-Ended (SE) channels with a fixed gain of 26 dB or one Bridge-Tied
Load (BTL) channel with a fixed gain of 32 dB.
The TFA9843J comes in a 9-pin DIL-bent-SIL (DBS) power package. The TFA9843J is
pin compatible with the TFA9842J and TFA9841J.
The TFA9843J contains a unique protection circuit that is solely based on multiple
temperature measurements inside the chip. This gives maximum output power for all
supply voltages and load conditions and no unnecessary audio holes. Almost any supply
voltage and load impedance combination can be made as long as thermal boundary
conditions (number of channels used, external heatsink and ambient temperature) allow it.
2)Features
n SE: 1 W to 20 W; BTL: 4 W to 40 W operation possibility
n Soft clipping
n Standby and mute mode
n No on/off switching plops
n Low standby current
n High supply voltage ripple rejection
n Outputs short-circuit protected to ground, supply and across the load
n Thermally protected
n Pin compatible with the TFA9842J and TFA9841J.

(2)function introduction to TDA8947J
1)Description
The TDA8947J contains four identical audio power amplifiers. The TDA8947J can be used as: four
Single-Ended (SE) channels with a fixed gain of 26 dB, two times Bridge-Tied Load (BTL) channels with a
fixed gain of 32 dB or two times SE channels (26 dB gain) plus one BTL channel (32 dB gain) operating as a
2.1 system.
The TDA8947J comes in a 17-pin Dil-Bent-Sil (DBS) power package. The TDA8947J is pin
compatible with the TDA8944AJ and TDA8946AJ.
The TDA8947J contains a unique protection circuit that is solely based on multiple
temperature measurements inside the chip. This gives maximum output power for all
supply voltages and load conditions with no unnecessary audio holes. Almost any supply
voltage and load impedance combination can be made as long as thermal boundary
conditions (number of channels used, external heatsink and ambient temperature) allow it.

n Soft clipping
n Standby and mute mode
n No on/off switching plops
n Low standby current
