ISL28110FBZ-T7A is a high performance, Ultralow distortion, zero-drift current feedback instrumentation amplifier (op amp). It has a wide operating supply voltage range of ±2V to ±60V, which makes it well suited for medical, test and measurement, motor control, industrial and consumer applications. The ISL28110FBZ-T7A is also ideal for precision current sense applications as it has two full rail-to-rail current sensing inputs and a dedicated current sense amplifier that operates from a single supply.

The ISL28110FBZ-T7A is a true instrumentation amplifier and provides the functions of a voltage amplifier, high pass filter, and low pass filter in one IC. It has built-in gain setting resistor, temperature compensation, and low output offset voltage. The product supports a wide common mode input from -7.5V to V- (minus supply). Its 2-MHz unity gain bandwidth and 52-V/μs slew rate make it suitable for high speed applications.

The working principle of the ISL28110FBZ-T7A is based on the current-feedback architecture. A pair of matched transistors are used as input buffers to provide high common-mode rejection, low noise, and low offset. The output stage of the ISL28110 is a fully complementary voltage amplifier, which provides rail-to-rail output. The gain of the instrumentation amplifier can be easily set by the two external resistor circuits.

The ISL28110FBZ-T7A can be applied in linear amplification, motor control, power supply, biomedical sensing, electronics between the interface and mechanical device, measurement and control systems, video signal conditioning, etc. For example, the instrumentation amplifier can be used to build a voltage-measuring circuit. The circuit consists of a set of outer resistor for setting the gain, an inner shunt resistor for measuring the current, and some externally connected resistor to prevent the injection of noise and polarization currents into the measurement.

Therefore, the ISL28110FBZ-T7A is a high-performance, cost-effective instrumentation amplifier that is ideal for a variety of industrial, consumer, automotive, and medical applications. The current-feedback architecture and the wide range of features make it suitable for a broad range of high speed applications where precision and stability are required.
