The INA2126EA/250 is a high-performance, high-gain instrumentation amplifier for applications in both precision and industrial settings. It is a low power, low noise, low-distortion amplifier that delivers excellent linearity, low drift, and low crosstalk between channels. This makes it a perfect choice for instrumentation, precision medical, industrial, and consumer electronics. Designed with a differential input stage and a buffered output stage, it provides excellent common-mode rejection, high-gain accuracy, and low noise. In addition, it offers a wide range of gain settings that can be adjusted with a single external resistor.

The amplifier comes in various packages: the INA2126EA/250 version comes in a 8-pin DIP or a 8-pin SOIC package. The INA2126 has two amplifier stages, the differential input stage (front end) and the buffered output stage. The front end consists of two matched PNP transistors and provides the input offset voltage (Vos) correction and the input frequency compensation. The buffered output stage is a low-gain unity-gain buffer made up of two matched NPN transistors, providing the high-gain accuracy, low noise, and low-level offset voltage.

The operating principle of the amplifier can be described in a few simple steps. The first step is the differential input stage, where the differential signals (two input signals of opposite polarity) are converted into a single-ended output signal. Then, the single-ended signal is amplified by the amplifying stage, which provides various gain settings. Finally, the buffered output stage amplifies the amplified signal delivered by the amplifying stage and drives the float circuit. This float circuit has a low threshold voltage, providing a very low output offset voltage.

The INA2126EA/250 instrumentation amplifier is well suited for a variety of applications such as audio detection, strain gauge measurements, biomedical instrumentation, electrical protection systems, digital thermometers, pH electronic meters, precision microphones, and bioimpedance measurements. In addition, the amplifier can be used for precision ADC/DAC interface circuit designs due to its excellent gain accuracy, low drift, and low noise. It is also a suitable choice for creative audio designs, such as active crossovers and loudspeaker management.

The INA2126EA/250 instrumentation amplifier is an ideal amplifier for a wide range of instrumentation and industrial applications. It comes in a variety of packages, has a wide range of gain settings, and provides excellent common-mode rejection, high-gain accuracy, and low noise. Additionally, it is a suitable choice for precision ADC/DAC interface circuit designs and also for creative audio designs.
