Intersil ISL28117 User Manual

40V Precision Low Power Operational Amplifiers
ISL28117, ISL28217, ISL28417
The ISL28117, ISL28217 and ISL28417 are a family of very high
precision amplifiers featuring low noise vs power consumption,
low offset voltage, low I current and low temperature drift
BIAS
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 ISL28117 single and ISL28217 dual are offered in an
8 Ld SOIC, MSOP and TDFN packages. The ISL28417 is offered
in 14 Ld SOIC, 14 Ld TSSOP packages. All devices are offered
in standard pin configurations and operate over the extended
temperature range from -40°C to +125°C.
