OPA2137EA/2K5

The OPA2137EA/2K5 is a low noise, precision dual operational amplifier (op amp) designed for use in instrumentation and general purpose signal acquisition applications. This op amp features high common mode rejection ratio (CMRR) and very low noise figure, making it ideal for a wide range of applications.

The OPA2137EA/2K5 is a unity gain stable device with a gain-bandwidth product of 5.5MHz and a guaranteed minimum common mode rejection ratio of 90dB. It is capable of accepting a single or dual (differential) input signals and providing an amplified single or dual output signal in response to the input. This op amp can be used as an amplifier or buffer in applications ranging from audio and acoustic equipment to biomedical instrumentation, scientific instrumentation and automotive systems.

The OPA2137EA/2K5 is designed to operate from a single supply voltage of 2.7V to 18V. It can accept input signals over a wide range, from DC to 150MHz, with a minimum slew rate of 40V/µs. The device is also capable of delivering up to 15mA of output current.

The OPA2137EA/2K5’s working principle is based on the basic operational amplifier design. The two input transistors of the op amp (the non-inverting and inverting sockets) create an internal differential amplifier circuit. The differential amplifier is then combined with an output amplifier to create an op amp which can process and amplify signals.

The input signal is applied to the non-inverting and inverting sockets which control the gates of the two transistors. This causes the transistors to generate a voltage difference between them. The output signal is then amplified by the output amplifier and is ready for use in the application.

The OPA2137EA/2K5 is designed to be used in a variety of applications such as signal acquisition, precision signal processing, medical device instrumentation, and power supplies. It is also suitable for use in audio and acoustic applications, including microphone pre-amplifiers, active filters, and instrument-grade speakers. Additionally, the OPA2137EA/2K5 is compatible with testing and monitoring systems, such as thermometers and pressure gauges.

The OPA2137EA/2K5 is a highly reliable and versatile operational amplifier manufactured to meet a variety of needs. Its low noise output, high CMRR, and capacity to operate with a single supply voltage make it an ideal choice for applications in linear, instrumentation, audio and scientific instrumentation.
