The ISL28117, ISL28217 and ISL28417 are a family of very high precision amplifiers featuring low noise vs power consumption, low offset voltage, low IBIAS current and low temperature drift making them the ideal choice for applications requiring both high DC accuracy and AC performance. The combination of precision, low noise, and small footprint provides the user with outstanding value and flexibility relative to similar competitive parts.

Applications for these amplifiers include precision active filters, medical and analytical instrumentation, precision power supply controls, and industrial controls.

The ISL28117 single and ISL28217 dual are offered in an 8 Ld SOIC, MSOP and TDFN packages. The ISL28417 is offered in 14 Ld SOIC, 14 Ld TSSOP packages. All devices are offered in standard pin configurations and operate over the extended temperature range from -40°C to +125°C.
