DATASHEET ISL28127, ISL28227, ISL28227SEH FN6633 Rev 8.00 April 1, 2016 Precision Single and Dual Low Noise Operational Amplifiers The ISL28127, ISL28227 and ISL28227SEH are very high precision amplifiers featuring very low noise, low offset voltage, low input bias 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 ISL28127 single and ISL28227 dual are available in 8 Ld SOIC, TDFN and MSOP packages. All devices are offered in standard pin configurations and operate over the extended temperature range to -40°C to +125°C. The ISL28227SEH is available in a 10 Ld hermetic ceramic Flatpack package. The device is offered in an industry standard pin configuration and operates over the extended temperature range from -55°C to +125°C.
