NJM2737D is a precision low-noise dual operational amplifier, which belongs to the category of linear amplifiers, instrumentationop amps, bufferamps. NJM2737D is an integrated circuit with two similar monolithic amplifiers, each of which consists of a transconductance amplifier-comparator and an output stage, designed and optimized for low-noise applications. The device is extremely useful in applications where the full rail-to-rail common mode range is not required, but low-noise performances are important.The core of NJM2737D is a transconductance amplifier-comparator, which is the combination of negative feedback amplifier, precision comparator and voltage to current converter. It works a staightforward manner. The negative feedback amplifier produces two outputs, which provides input signals to the comparator. The comparator compares the two signals and produces a digital output signal. Then, the voltage to current converter converts the digital output signal into a current output.

NJM2737D offers significant benefits in terms of low-noise performance and low power consumption. According to the datasheet, NJM2737D can achieve an output noise voltage of 5nV/√Hz, a supply current of 1.5µA/amplifier, and a low power consumption of 10mW per amplifier, making it an ideal choice for high-quality audio applications. Furthermore, NJM2737D provides a wide gain bandwidth of 1MHz, which is suitable for low-noise audio amplifiers, instrumentation amplifiers, and voltage-to-current converters. In addition to its low-noise performance, NJM2737D also offers excellent common-mode rejection ratio (CMRR) and good linearity. Achieving an impressive CMRR of 90dB at 1kHz, NJM2737D ensures that signals that are common to both inputs of the op amp will be rejected, thereby eliminating the need for an external input filter when used in balanced input configurations. Moreover, NJM2737D provides excellent linearity up to 1kHz, making it suitable for applications where linear operation is required, such as amplification of low-frequency signals. In summary, NJM2737D is an ideal choice for high-quality low-noise audio and instrumentation applications, due to its low-noise performance, low power consumption and wide gain bandwidth. Furthermore, its excellent common-mode rejection ratio and good linearity make NJM2737D a reliable and effective amplifier for a variety of applications.
