OPA251UA/2K5 is a high-performance amplifier with low offset voltage, low noise, and high slew rate. It is a monolithic integrated circuit with a single-ended input and output designed for low power applications such as instrumentation and measurement.

The OPA251UA/2K5 is a bipolar device that utilizes a dual-stage high bandwidth amplifier with complementary outputs, allowing for a wide variety of applications when compared to single-stage amplifiers which typically have limited capabilities.

The OPA251UA/2K5 is commonly used in instrumentation and measurement systems as it has wide frequency- and gain-bandwidths, and low offset drift. It can also be used in medical applications due to its configurable input/output impedance, low power consumption and large current swing capability.

The OPA251UA/2K5 is typically used as an operational amplifier with an op-amp gain of up to a few hundred depending on the application. By adding both feedback and gain-setting resistors to the circuit, the OPA251UA/2K5 can be used to amplify signals with a wide range of gains.

The OPA251UA/2K5 can also be used as a buffer amplifier, with a gain of less than one. This type of amplifier is typically used to increase the driving capability of a signal source while maintaining the low power consumption and wide frequency response of the OPA251UA/2K5.

The OPA251UA/2K5 has a wide variety of applications due to its low noise and high slew rate. It can be used for ADCs and DACs, for power-supply line isolation, audio amplification and oscilloscope input buffering.

The OPA251UA/2K5 can be used in several common circuit configurations, including single-ended, differential, and instrumentation amplifiers. In some applications, the inverting gain can be increased even further by cascading two OPA251UA/2K5s in series.

The working principle of the OPA251UA/2K5 is identical to that of any other operational amplifier. It has two inputs: one non-inverting input and one inverting input. It also has an output, which is a function of the difference between the two inputs.

The OPA251UA/2K5 amplifies the difference between its two inputs with a fixed gain, which can be set by connecting external resistors to its two input nodes. This amplified difference is then provided at the output.

In summary, the OPA251UA/2K5 is a high-performance instrumentation and measurement device used in a variety of applications. It has a low offset voltage, low noise, and wide frequency response. It can be used as an operational amplifier or as a buffer amplifier. Its working principle is identical to that of any other operational amplifier.
