ISL28127, ISL28227

Precision Single and Dual Low Noise

Operational Amplifiers

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 is available in an 8 Ld SOIC package.

The ISL28227 dual amplifier will be offered in 8 Ld SOIC

package. All devices are offered in standard pin

configurations and operate over the extended temperature

range to -40°C to +125°C.
