INA2126E/250 is a low-cost monolithic instrumentation amplifier with a single-ended input and full-scale to ±250 mV. It is high common-mode rejection (CMR), low-noise, low-distortion and low-power instrumentation amplifier with high gain accuracy and fast settling time. It is suitable for a wide range of applications, including industrial, automotive and instrumentation applications.

The main applications for the INA2126E/250 include signal conditioning, data acquisition systems, loop-power supply, low-level signal processing, and low-level audio applications. Its low-noise and high-CMR feature makes it ideal for applications where common-mode noise is a major problem. Additionally, its high-gain accuracy feature makes it useful in applications that require precision control of the gain. Furthermore, due to its fast settling time, it is also suitable for time-sensitive applications.

The INA2126E/250 features a unique design, consisting of a single wide-band differential amplifier, a gain-setting stage, and a low-power output amplifier. The wide-band differential amplifier is used to accept an input signal and rejects common-mode noise. This is then followed by the gain-setting stage, which is used to set the overall gain of the amplifier, ranging from 1 to 100. Finally, the relatively low-power output amplifier is used to drive the output signal with minimal distortion.

In terms of performance, the INA2126E/250 has an excellent noise performance, with a typical noise floor of 20 mV p-p. The CMR is also excellent, with a typical value of 70 dB. The slew rate is also good, with a typical value of 2 V/μs. The amplifier also offers high-accuracy gain settings, with a typical precision of 0.1% over the entire range of gains. The settling time is also fast, with a typical settling time of 10 μs.

Overall, the INA2126E/250 is a high-performance, low-cost instrumentation amplifier. It offers excellent noise performance, high CMR, and high-accuracy gain settings and fast settling time, making it ideal for a wide range of applications, including signal conditioning, data acquisition systems, loop-power supply, low-level signal processing and low-level audio applications.
