Features

NJU4052BD has an output voltage range of 0.9V to 12V for both channels. It can provide a wide range of impedance matching capability and has excellent EMI-rejection and line transient protection. NJU4052BD also includes a Low Noise amplifier (LNA) and a high-performance MOSFET switch to provide low distortion and distortion-free switching for high-performance audio applications. The device also features low power consumption, low distortion, and high-linearity.

Application Field

NJU4052BD can be found in several applications and can be used in multiplexer/demultiplexer, analog switches, active filters and pre-amplifier applications. It is highly suitable for audio and multimedia system solutions, such as high fidelity, active filters and equalizers, loudspeakers, computers, recording and monitoring, interactive voice response, audio metrics and professional audio. In addition, NJU4052BD is suitable for use in wireless systems where low power consumption, low distortion and high linearity are desired.

Working principle

NJU4052BD is a double transistor amplifier, featuring low power consumption, low distortion and high linearity. The amplifier consists of two transistors connected in series, one of them acts as the input stage and the other acts as the output stage. The amplifier receives an input signal at the input stage and amplifies it before sending it to the output stage. The output stage then sends the signal to the amplifier’s output. The amplifier’s output can then be used as the input to other circuits or devices.

Conclusion

NJU4052BD is an amplifier IC developed by NJRS semiconductor company. It is a dual transistor amplifier with low power consumption and high linearity. It can be used in multiplexer/demultiplexer, analog switches, active filters and pre-amplifier applications for which low power consumption, low distortion and high linearity are desired. NJU4052BD features low power consumption, low distortion, and high-linearity and is suitable for use in wireless systems as well. The amplifier consists of two transistors connected in series, one of them acts as the input stage and the other acts as the output stage.
