The INA2128UA/1K is a highly high-performance instrumentation amplifier designed for precision-sensitivity signal conditioning, signal isolation, and general-purpose variable-gain operations. The performance of this device is unmatched for differentiating input sources, and for high-output signal amplification. This device is able to maximize the performance of precision signal conditioning system.

The INA2128UA/1K is a low-cost instrumentation amplifier. This device consists of 6 operational amplifiers, 8 resistors, and 4 capacitors, depending on the configuration. It is a 3-Stage amplifier with high input impedance and low output impedance, making it well-suited for a variety of variable gain, offset voltage, and signal amplification applications. It is designed to provide wide dynamic range and low noise, making it a preferred choice for applications requiring precision control of the amplified signal.

The INA2128UA/1K offers flexibility to meet precise design requirements, as it can be configured to amplify signals down to 0.1 μV (microvolts). The input voltage range is extends to ±25V, while the DC power supplies offer a voltage range of ±2.7V to ±36V, making it compatible with virtually any system. In addition, the device can be configured to have an overall gain of up to 40,000V/V (volt per volt).
