Details
General descriptionThe TFA9842AJ contains two identical audio power amplifiers. The TFA9842AJ can be used as two Single-Ended (SE) channels with a volume control. The maximum gain is 26 dB.The TFA9842AJ comes in a 9-pin DIL-bent-SIL (DBS9P) power package. The TFA9842AJ is pin compatible with the TFA9843AJ, TFA9843(B)J, TFA9842(B)J and TFA9841J. The difference between the TFA9843AJ and the TFA9843(B)J, TFA9842(B)J, TFA9841J is the functionality of pin 7. The TFA9843AJ has a Volume Control (VC) on pin 7. The TFA9843(B)J, TFA9842(B)J and TFA9841J have a mode select (MODE) on pin 7.The TFA9842AJ 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.Features■ 2 channel SE: 1 W to 7.5 W operation possibility■ Soft clipping■ Input clamps■ Volume control■ 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 TFA9843AJ, TFA9843(B)J, TFA9842(B)J and TFA9841JApplications■ CRT TV and LCD TV■ Monitors■ PC speakers■ Boom box■ Mini and micro audio receivers

FAQs
What is TFA9844J?
The TFA9844J is a 5-Watt (RMS) stereo audio power amplifier integrated circuit designed for driving stereo speakers in various audio applications. It is commonly used in consumer electronics such as TVs, portable speakers, and home audio systems.
How Does TFA9844J Work?
The TFA9844J works by amplifying low-power audio signals from a source such as a mobile phone, MP3 player, or audio processor and driving them into stereo speakers with sufficient power for audible sound reproduction. The amplifier features protection circuitry to safeguard the device and speakers from potential damage due to overloads or faults.
How Many Pins does TFA9844J have and What are the Functions of the Pinout Configuration?
The TFA9844J is housed in a 9-pin SIL (Single In-Line) package. The pinout configuration includes:
- VCC: Positive power supply pin.
- VDD: Positive power supply for preamplifier stage.
- VSS: Ground pin.
- MODE: Mode select pin for stereo and bridged configurations.
- ST-BY: Standby pin for power control.
- OUT1 and OUT2: Output pins for the left and right channels, respectively.
- FILT: Pin for external noise filter connection.
What are the Pros and Cons of TFA9844J?
Pros:
- High Power Output: Capable of driving stereo speakers with 5 watts RMS per channel.
- Protection Features: Includes protection against short circuits, thermal overload, and DC offset.
- Space-Efficient Package: The 9-pin SIL package is compact and suitable for space-constrained designs.
- Low External Component Count: Requires minimal external components for operation.
- Wide Supply Voltage Range: Supports a wide voltage supply range for flexibility in different applications.
Cons:
- External Heat Sink: May require an external heat sink for high-power applications and extended operation.
- High Power Dissipation: Generates heat during high-power operation, requiring thermal management considerations.
- Resource Limitations: Limited to stereo audio amplification and may not be suitable for multi-channel applications.
Are There Any Equivalents/Alternatives to TFA9844J for Recommendation?
- The TDA7265 from STMicroelectronics is a similar 5-Watt stereo audio power amplifier with comparable features.
- Alternatives to the TFA9844J include the LM1875 from Texas Instruments and the NJM2073D from New Japan Radio.
