Precision Single, Dual and Quad Low Noise Operational Amplifiers
ISL28107, ISL28207, ISL28407
The ISL28107, ISL28207 and ISL28407 are single, dual and quad amplifiers featuring low noise, low input bias current, and low offset and temperature drift. This makes 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 ISL28107 is available in an 8 Ld SOIC, MSOP and TDFN package. The ISL28207 is available in the 8 Ld SOIC and MSOP packages. The ISL28407 will be offered in an 14 Ld SOIC, TSSOP and 16 Ld QFN packages. All devices are offered in standard pin configurations and operate over the extended temperature range to -40°C to +125°C.
