TFA9841J
General description
The TFA9841J contains one audio power amplifier. The TFA9841J can be used as one Single-Ended (SE) channel with a fixed gain of 26 dB.
The TFA9841J comes in a 9-pin DIL-bent-SIL (DBS9P) power package. The TFA9841J is pin compatible with the TFA9842J and TFA9843J.
The TFA9841J 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 (external heatsink and ambient temperature) allow it.
Features
- SE: 1 W to 7.5 W (into 4 Ohm), up to 9 W into (into 8 Ohm)
- Soft clipping
- Standby and mute mode
- No on/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 TFA9842J and TFA9843J.
