Precision Single and Dual Low Noise Operational Amplifiers ISL28107 and ISL28207 The ISL28107 and ISL28207 are single and dual 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 single is available in an 8 Ld SOIC package. The ISL28207 dual amplifier will be offered in an 8 Ld SOIC package. All devices are offered in standard pin configurations and operate over the extended temperature range to -40°C to +125°C.
