Working Principle

The ISL28168FHZ-T7 uses precision current-mode circuitry to amplify analog signals and produce a high-precision output. This amplifier features an input stage composed of two differential amplifiers, each one containing two transistor devices. The first differential amplifier amplifies the input signal and the other differential amplifier inverts it. The output of the inverted amplifier is then summed with the non-inverted signal of the first amplifier. This summing action produces a differential analog output signal suitable for further processing. The second stage of the amplifier is a gain-setting stage which is used to set the gain of the output signal. This gain-setting stage is controlled by two external resistors and has a range of gains from 0.1 - 10. The output of the amplifier is a high-precision signal suitable for further processing. The ISL28168FHZ-T7 amplifier is powered by +5V and can be used with +/- 15V supplies.
