ISL28207

Precision Dual Low Noise Operational Amplifier

OVERVIEW

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 8 Ld SOIC, MSOP and TDFN packages. The ISL28207 is available in 8 Ld SOIC, MSOP and TDFN packages. The ISL28407 is available in a 14 Ld SOIC package. All devices are offered in standard pin configurations and operate over the extended temperature range of -40°C to +125°C.
