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-to-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.
