TFA9842

2-channel audio amplifier; SE: 1 W to 7.5 W; BTL: 2 W to 15 W

 

 

General description

The TFA9842J contains two identical audio power amplifiers. The TFA9842J ca be

used as two Single-Ended (SE) channels with a fixed gai of 26 dB or one

Bridge-Tied Load (BTL) channel with a fixed gai of 32 dB.

The TFA9842J comes i a 9-pi DIL-bent-SIL (DBS9P) power package. The

TFA9842J is pi compatible with the TFA9841J and TFA9843J.

The TFA9842J contains a unique protectio circuit that is solely based o 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 combinatio ca be made as long as thermal

boundary conditions (number of channels used, external heatsink and ambient

temperature) allow it.
