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.
