40V Low Power Dual and Quad Operational Amplifier

ISL28325, ISL28345

The ISL28325 and ISL28345 are dual and quad general purpose

amplifiers featuring low noise vs power consumption. The

combination of low noise and small footprint provides the user with

outstanding value and flexibility relative to similar competitive parts.

Applications for this amplifier include active filters, medical and

analytical instrumentation, power supply controls, and industrial

controls.

The ISL28325 is offered in 8 Ld SOIC and MSOP packages and

the ISL28345 is offered in the 14 Ld SOIC package and operates

over the -40°C to +125°C temperature range.
