Working Principle

The ISL28138FHZ-T7 is a high performance operational amplifier that has a rail-to-rail input and output swing. It is designed to operate from a single 1.8V to 5.5V supply and still deliver rail-to-rail performance. The output swing is limited only by the output voltage swing of the power supply and the load resistor values. The quiescent current of the ISL28138FHZ-T7 is very low, resulting in very low power consumption.

The amplifier is designed so that the quiescent drain current is minimized over the full input voltage range. It also has a very low input bias current and a low input/output capacitance, which makes it ideal for use in high-impedance applications with low power requirements. The amplifier also provides ESD protection to the input and output pins.

The ISL28138FHZ-T7 opeartional amplifier has the advantage of excellent DC precision, low offset voltage and low noise. These features make it an ideal choice for applications where precise DC performance is required. It also offers high noise immunity and low distortion which make it ideal for precision signal processing.
