ISL28290FBZ-T7 Application Field and Working Principle

The ISL28290FBZ-T7 is a low-noise, low-current operational amplifier (op amp) with an amplifier bandwidth of 1.2GHz and typical unity gain bandwidth of 240MHz. It is capable of driving loads as low as 8Ω with excellent linearity and transient response. It is designed to provide superior performance in portable and industrial instrumentation, medical electronics, audio amplifiers, and power supply applications.

The ISL28290FBZ-T7 is a single-package, single-supply CMOS op amp. It features an input voltage range of -2.5V to +2.5V, an output voltage range of -20V to +20V, and an output drive current of 10mA (max). It is capable of delivering up to 8V of output drive voltage with a gain of 500V/V. The gain is adjustable using external resistors, making it suitable for use as a unity-gain buffer amplifier with excellent linearity and transient response.

The ISL28290FBZ-T7 employs a folded-cascode topology, which has a higher differential gain, lower output impedance and input noise, and better linearity compared to conventional single-stage op amps. The use of on-chip MOSFET transistors enables fast slew rate and high input and output current drive capability. The gain stability is superior over supply and temperature, allowing it to be used in many precision and low-power applications.
