The NJM2521D is a special purpose audio amplifier class integrated circuit designed and developed by New Japan Radio (NJR) Corporation in the late 20th century. This integrated circuit is mainly intended for use in audio applications, such as sound reinforcement and professional audio equipment. This integrated circuit can also be applied in some consumer electronics, such as television sets and radios. As an audio amplifier, the NJM2521D can provide high power output, low distortion output and low noise floor while it consumes less power compared to other amplifier circuits.
The NJM2521D is a complementary bipolar amplifier circuit featuring two differential input stages capable of yielding up to 75 watts of peak output. This amplifier uses two bipolar transistors fabricated on a single chip. The operating voltage for the NJM2521D is 6.0V with a maximum voltage of 8.0V. The operating frequency range of this amplifier is 10kHz to 200kHz. The total harmonic distortion (THD) of the NJM2521D is rated at 0.02%, while its output power is rated at 75W. The operating temperature of the NJM2521D is -40°C to 85°C.
In terms of the NJM2521D\'s working principle, the input stage consists of two transistors, a current source and an isolation resistor. The isolation resistor isolates the two circuits, allowing only a portion of the signal to pass through. The current source acts as a reference voltage for the transistors and allows for symmetrical gain operating characteristics. The second stage is a voltage-controlled class A amplifier, which increases the current in decision to the input signal level. Finally, the output stage is a class B amplifier, which amplifies the signal to provide the desired gain.
The NJM2521D is exceptionally well suited for audio applications, such as sound reinforcement and professional audio equipment. It is suitable for controlling high power speakers, such as loud speakers and subwoofers. It is also great for applications that need low distortion, such as pre-amps, compressors, limiters, and audio signal processors. This integrated circuit is able to provide high power output and low distortion levels, while consuming less power compared to other amplifier circuits. This makes the NJM2521D an ideal choice for audio applications.
Overall, the NJM2521D is a high-performance audio amplifier circuit designed and developed by New Japan Radio Corporation specifically for use in various audio applications. It is able to provide high power output and low distortion levels, while consuming less power compared to other amplifier circuits. The NJM2521D is highly suited for professional audio equipment, sound reinforcement systems, and a variety of audio applications requiring low distortion and high power output.
