The INA128U/2K5G4 is an instrumentation amplifier and buffer amp designed for a variety of applications that require high-precision, high accuracy signal amplification and buffering. It is a dual-channel device, with each channel offering up to 2.5kΩ input impedance and balanced output. The INA128U/2K5G4 helps to provide signal conditioning for a variety of applications, including low-voltage, low-frequency signal conditioning, signal amplification and buffering, and waveform conversion.

One of the key advantages of the INA128U/2K5G4 lies in the fact that the amplifier has an operating range of 0V to 2.5V, making it ideal for use in a variety of low-voltage systems, including remote monitoring and control systems and low-power applications. Additionally, the linear gain range of the amplifier is wide and can range from 1 to 100 V/V, allowing for a variety of gain levels to be achieved. This also allows for flexible gain controls, as the amplifier can be operated at any gain level between its rated upper and lower limits.

The INA128U/2K5G4 amplifier is designed to reduce unwanted DC and AC offsets, as it has a low-noise clock input section, an improved high-voltage output drive capability, and a wideband low-distortion gain. The low-noise clock input section of the amplifier helps to reduce unwanted electrical noise, as it does not amplify any noise that is present in input signals. As well, the improved high-voltage output drive ability helps to reduce losses in signal power as the signal travels from the amplifier to its output boosters.

The amplifier also provides high-precision low-offset voltage control capabilities. By utilizing a programmable common-mode voltage gain and an adjustable output voltage swing for dynamic voltage control, the INA128U/2K5G4 can accurately set the voltage level of its output. The amplifier also features an adjustable common-mode voltage compensation feature, which helps to reject input signals that are too small or too large in amplitude.

The INA128U/2K5G4 also features ultra-low distortion operation, as its pulse feedback pairing technology allows for precise linearity with minimal non-linear components. The low distortion benefits are also complemented by a high peaking performance, extended frequency response and low noise performance, providing wideband solutions for a variety of applications. The amplifier’s higher 3dB frequency achieves narrower ripples and flatter passbands, resulting in higher accuracy and reliability.

The INA128U/2K5G4’s features make it suitable for a variety of applications, such as audio and video amplification, differential and single-ended measurements, power supplies, active filters, motor control, and noise cancellation systems. Additionally, it is an excellent choice for remote sensing applications, as its low power consumption and wide operating temperature range make it an ideal solution for battery-powered systems. Because of its small package size and low system noise, the INA128U/2K5G4 is also a good solution for instrumentation, medical, and automotive applications.
