ISL28117 Datasheet, PDF (1/18 Pages) Intersil Corporation – 40V Precision Low Power Operational Amplifiers

40V Precision Low Power Operational Amplifiers
ISL28117, ISL28217
The ISL28117 and ISL28217 are a family of very high
precision amplifiers featuring low noise vs power
consumption, low offset voltage, low I_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 ISL28117 single and ISL28217 dual are offered in an
8 Ld SOIC package. Both devices are offered in standard
pin configurations and operate over the extended
temperature range to -40°C to +125°C.
