ISL28227

® ISL28127, ISL28227 Data Sheet May 29, 2009 FN6633.0 Precision Single and Dual Low Noise Operational Amplifiers The ISL28127 and ISL28227 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 is available in an 8 Ld SOIC package. The ISL28227 dual amplifier will be offered in 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.
