40V Extended Temperature Range, Precision

Single-Supply, Rail-to-Rail Output, Operational Amplifier

ISL28118M

The ISL28118M is a single, low-power precision amplifier

optimized for single-supply applications over the extended

temperature range of -55°C to +125°C. This device features a

common mode input voltage range extending to 0.5V below

the V- rail, a rail-rail differential input voltage range for use as a

comparator, and rail-to-rail output voltage swing, which makes

it ideal for single-supply applications where input operation at

ground is important.

The ISL28118M features low power, low offset voltage, and

low temperature drift, making it the ideal choice for

applications requiring both high DC accuracy and AC

performance. The op amp is designed to operate over a single

supply range of 3V to 40V or a split supply voltage range of

+1.8V/-1.2V to ±20V. The combination of precision and small

footprint provides the user with outstanding value and

flexibility relative to similar competitive parts.

Applications include precision instrumentation, data

acquisition, precision power supply controls, and industrial

controls.

The ISL28118M is offered in the 8 Ld MSOP package and

operate over the extended temperature range of -55°C to

+125°C.
