Precision Single and Dual Low Noise Operational
Amplifiers
ISL28127, ISL28227
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 and ISL28227 dual are available in
an 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.
