Parameter introduction
The TDA2040 is available in a 14-pin multi-chip package and contains two independent audio power amplifiers. Each amplifier outputs up to 20W and is capable of driving 4Ω to 16Ω loads. The operating voltage of TDA2040 is 8V to 30V, and the maximum output voltage can reach 44V. In the frequency range of 20Hz to 20kHz, TDA2040 has a total harmonic distortion rate of only 0.08%, with extremely low noise and crossover distortion characteristics, ensuring high-quality audio output.
Development History
TDA2040 is a power amplifier chip launched by ST, and its predecessor is TDA2030. TDA2030 is a low-cost power amplifier widely used in audio equipment with good performance and reliability. With the continuous development of audio equipment and changes in market demand, TDA2030 can no longer meet users' requirements for high-fidelity sound quality. Therefore, ST has developed TDA2040 based on TDA2030, which adopts new process technology and design concepts for higher performance and reliability and has been widely recognized and applied in the market.
TDA2030AH, TDA2030AV, TDA2030H, and TDA2030V, are all audio power amplifier ICs of the TDA2030 series, click for more details.
TDA2040H and TDA2040V are two different packages of TDA2040, where H means horizontal package and V means vertical package.
TDA2040H is a horizontal multi-chip package, and its pin layout is along the horizontal direction, similar to the traditional TO-220 package. This package is suitable for applications where a power amplifier needs to be installed in a small space. The TDA2040H has a maximum operating temperature of 150°C, making it suitable for applications in high-temperature environments.
TDA2040V is a vertical multi-chip package, and its pin layout is along the vertical direction, which is suitable for applications requiring higher power, such as car audio. The maximum operating temperature of TDA2040V is 125°C, which can meet the requirements of most applications.
Whether it is TDA2040H or TDA2040V, their parameters, and performance are the same as TDA2040, all adopt a 14-pin multi-chip package, including two independent audio power amplifiers. The output power of each amplifier is up to 20W, capable of driving a load from 4Ω to 16Ω, the total harmonic distortion rate is only 0.08%, and has extremely low noise and crossover distortion characteristics, ensuring high-quality audio output. At the same time, TDA2040H and TDA2040V also have functions such as current protection and overheating protection, which can ensure the safe and stable operation of the equipment.
