INA126U/2K5 is an instrumentation amplifier used for a variety of applications. The device is especially well-suited for single-supply applications, as well as for low-voltage and low-power applications.

The INA126U/2K5 consists of two matched, high-impedance, low-noise amplified inputs and a differential output stage. The device also includes a wideband output amplifier, adjustable gain, DC restore and voltage buffer stages. These features make it an ideal choice for use in instrumentation, audio, and telecom applications.

The INA126U/2K5 has an adjustable gain range of 0-20V/V and can be operated with a single power supply. The device is also equipped with an open-loop gain of 2000. The voltage buffer stage has a Common Mode Rejection Ratio (CMRR) of -70 dB at 400 Hz and -60 dB at 1kHz.

The INA126U/2K5 is designed to operate with an input range of 0-3V, with a maximum single-ended output of 1V. The differential input can be configured for either single-ended differential or bipolar differential operation. The device also has a dynamic range of 105 dB, with a maximum output current of 5A.

The INA126U/2K5 is also a universal current sense amplifier, as it is capable of amplifying small differential or single-ended signals to generate a linear low-voltage output. The current sense gain can be programmed from 0.39 to 400V/V.

The INA126U/2K5 can also be used for bridge applications such as DC-regulated power supplies and charge pumps. In this application, the INA126U/2K5 can be used for low-frequency attenuation and high-frequency rejection as well as for controlling the output of the power supply.
