Precision Single, Dual and Quad Low Noise Operational

Amplifiers

ISL28107, ISL28207, ISL28407

The ISL28107, ISL28207 and ISL28407 are single, dual and

quad amplifiers featuring low noise, low input bias current,

and low offset and temperature drift. This makes 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 ISL28107 is available in 8 Ld SOIC, MSOP and TDFN

packages. The ISL28207 is available in 8 Ld SOIC, MSOP and

TDFN packages. The ISL28407 is available in a 14 Ld SOIC

package. All devices are offered in standard pin configurations

and operate over the extended temperature range of -40°C to

+125°C.
