Linear - Amplifiers - Instrumentation, OP Amps, Buffer Amps The OPA4703EA/2K5 is a linear amplifier instrumentation amplifier (OP Amp) and buffer amplifier that is available for purchase for various applications. It is a monolithic amplifier system consisting of an operational amplifier (OP Amp), unity gain buffer (UGB), and reference gain amplifier (RGA). This device combines the high performance of an OP Amp and the high slew rate of a UGB to deliver low distortion, low noise, and low offset voltage.This device is designed to provide high precision gain, accuracy, and stability under all operating conditions. Its performance is ideal for precision instrumentation, buffering, video, audio, and communications applications. Its features include low noise, low distortion, high gain accuracy, low offset voltage, and wide supply range.The OPA4703EA/2K5 amplifier features a fully differential input and output stage, allowing for a wide range of high performance applications. It has an operating temperature range of -40°C to 125°C and is capable of operating from a single supply of 4.5V to 15V. It offers an open loop gain of 120dB (typ) with a total harmonic distortion (THD) of 0.002% (typ), and it is capable of providing a maximum output current of 15mA. It also provides a maximum output voltage swing of 300mV.The OPA4703EA/2K5 also features a precision voltage reference, allowing for the compensation of offset voltages and eliminating the need for external voltage trimming. This reference allows for high accuracy, low drift, and improved low frequency/high frequency performance. The reference is adaptive and can be programmed to any voltage between 3.3V and 10.8V.The OPA4703EA/2K5 enables users to create custom designs with ease. The device can be used to design an amplifier with low noise, low distortion, high gain accuracy, and low offset voltage. It is able to perform precision instrumentation operations, buffering, and communication applications.The OPA4703EA/2K5 amplifier’s working principle can be summarized as follows. The device contains separate OP Amp and UGB blocks, both of which are connected to the input and output terminals. The input signal is first amplified and buffered by the OP Amp, with the output of this stage then provided to the UGB. The UGB amplifies the OP Amp output and provides the control voltage to the compensator to keep the output parameters constant. The reference amplifier then provides the main amplification, with the output of this stage then sent out of the device to the output terminal.In conclusion, the OPA4703EA/2K5 is a high performance linear amplifier instrumentation amplifier that offers a range of features and benefits to users. Its low noise, low distortion, high gain accuracy, low offset voltage, and wide supply range make it ideal for a range of applications, such as precision instrumentation, buffering, video, audio, and communications. Its simple and highly versatile design enables users to build custom designs with ease. Its precision reference voltage also allows for the compensation of offset voltages and eliminates the need for external voltage trimming.
