DATASHEET
ISL28118M
40V Extended Temperature Range, Precision Single-Supply, Rail-to-Rail Output,
Operational Amplifier
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.

NOTES:
1. Add “-T*” suffix for tape and reel. Please refer to
TB347
for details on reel specifications.
2. These Intersil Pb-free plastic packaged products employ special Pb-free material sets, molding compounds/die attach materials, and 100% matte
tin plate plus anneal (e3 termination finish, which is RoHS compliant and compatible with both SnPb and Pb-free soldering operations). Intersil
Pb-free products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
3. For Moisture Sensitivity Level (MSL), please see product information page for
