NJM5532DD is a dual low-noise, high-gain audio amplifier designed for a variety of instrumentation, and audio preamplification application. The NJM5532DD is designed to be used in either formal or general-purpose industrial equipment.

The NJM5532DD amplifier is composed of a pair of complementary circuits called "inputs" and "outputs", each having a differential pair of transistors (N-type and P-type) to provide maximum efficiency and reliability. The inputs are common-mode feed-forward gain stabilized, which ensures a low noise and distortion performance.

The NJM5532DD has a low-noise, high-gain design with a maximum gain of up to 1000 (or 52 dB). This feature makes NJM5532DD suited for amplifying signals which are too small for traditional amplifiers to measure. It is suitable for instrumentation purposes such as voice amplifiers, sound level meters, preamplifiers and microphones.

The NJM5532DD employs a modified Miller effect structure, which uses a dual-stage amplifier circuit capable of providing extremely wide frequency responses. This ensures a wide range of gain responses due to its very low bias current. This enables the NJM5532DD to accurately reproduce complex electronic signals with low distortion and noise, making it suitable for any type of data acquisition almost immediately.

The NJM5532DD also provides a wide range of temperature and humidity protection, which ensures reliable performance in a variety of environmental conditions. It also offers a wide range of supply voltages, ranging from 7V to 30V, and its low-impedance output stages ensure efficient current delivery and power efficiency.

In addition to its excellent amplification performance, the NJM5532DD is also capable of providing extremely low output impedance, making it ideal for applications that require extremely low-impedance drives such as moving coils, headphones, and loudspeakers. The NJM5532DD amplifier is also compatible with a range of power-supply regulators, making it easy to use in many different applications.

In terms of performance, NJM5532DD has excellent characteristics compared to other amplifiers. When used as a preamplifier, the NJM5532DD has a noise figure of less than 0.1dB and a THD+N of 0.0018%, due to its very low bias current. It also has a wide dynamic range and excellent linearity. Its low-noise performance makes it ideal for very sensitive instruments.

In terms of overall performance, the NJM5532DD is one of the most reliable and efficient linear amplifiers on the market today. It offers excellent performance for instrumentation and audio preamplification applications that require wide frequency responses and low output impedances. It features low-noise and distortion, wide dynamic range, and excellent linearity, making it a great choice for a wide range of applications.
