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.
