Linear - Amplifiers - Audio

The TDA1519CTH/N3C is a high-performance audio linear amplifier assembled in a 4-pin single-in-line package, with improved performance over the standard TO105 package. The amplifier is designed to meet the requirements of RB-DB (direct connection) applications, such as car audio and Hi-Fi systems. It is a very cost-effective product for these applications and provides an excellent price-to-performance ratio. The TDA1519CTH/N3C is designed to operate from a single supply voltage, typically 5V or 12V, and has a high output current capability. The device is suitable for driving a variety of loads and can deliver up to 2.1A at the output. The output stage is protected against short circuit.

Application Fields

The TDA1519CTH/N3C is used in a variety of audio applications, including car audio systems, Hi-Fi systems, home theater systems, portable audio systems, and multimedia systems. The device is also suitable for audio input and output amplifiers in other applications such as video cameras, Personal Digital Assistants (PDAs), monitor speakers, portable DVD players, and other consumer electronics. It is also suitable for voice-over-IP (VoIP) telephone applications.

Working Principle

The TDA1519CTH/N3C is an audio linear amplifier, which means it is designed to amplify a signal without introducing any distortion. The amplifier is based on a classic voltage amplifier circuit using bipolar transistors. The transistors operate as voltage amplifiers and are connected to two outer feedback resistors to form a two-stage amplifier. The two feedback resistors ensure that the amplifier output is accurately proportional to the input signal, regardless of any variations in the circuit.

The amplifier is designed to drive a wide range of loads, from 10 ohms up to 32 ohms. The output stage of the TDA1519CTH/N3C is protected against short circuit and the thermal shutdown ensures that the amplifier can operate in a wide range of ambient conditions. The amplifier also features a variety of safety features, such as a thermal shutdown and overcurrent protection, to ensure that the device is protected against excessive loads and/or current. The device also features a voltage-clamp circuit to protect the amplifiers against overvoltage.

Conclusion

The TDA1519CTH/N3C is a high-performance audio linear amplifier that is suitable for a variety of applications. It is designed to drive a wide range of loads, from 10 ohms to 32 ohms, and is protected against both short circuit and overvoltage. It also features thermal shutdown and overcurrent protection to ensure safe operation. It is an excellent choice for audio systems, as its price-to-performance ratio is very good.
