TFA9843BJ

2-channel audio ampliﬁer (SE: 1 W to 20 W)

Rev. 01 — 4 May 2004

Preliminary data sheet

1. General description

The TFA9843BJ contains two identical audio power ampliﬁers. The TFA9843BJ can be

used as two Single-Ended (SE) channels with a ﬁxed gain of 26 dB.

The TFA9843BJ comes in a 9-pin DIL-bent-SIL (DBS9P) power package. The TFA9843BJ

is pin compatible with the TFA9841J, TFA9842J, TFA9842BJ and the TFA9843J.

The TFA9843BJ 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.

2. Features

■ 1 W to 20 W operation possibility

■ Soft clipping

■ Standby and mute mode

■ No on or off switching plops

■ Low standby current

■ High supply voltage ripple rejection

■ Outputs short-circuit protected to ground, supply and across the load

■ Thermally protected

■ Pin compatible with the TFA9841J, TFA9842J, TFA9842BJ and the TFA9843J.

3. Applications

■ Televisions

■ Monitors

■ PC speakers

■ Boom boxes

■ Mini and micro audio receivers.
