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.
