40V Precision Single-Supply, Rail-to-Rail Output,
Low-Power Operational Amplifiers
ISL28118, ISL28218
The ISL28118 and ISL28218 are single and dual, low-power
precision amplifiers optimized for single-supply applications.
These devices feature 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 them ideal for single-supply
applications where input operation at ground is important.
These op amps feature low power, low offset voltage, and low
temperature drift, making them the ideal choice for
applications requiring both high DC accuracy and AC
performance. These amplifiers are 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 for these amplifiers include precision
instrumentation, data acquisition, precision power supply
controls, and industrial controls.
Both parts are offered in 8 Ld TDFN, 8 Ld SOIC and 8 Ld MSOP
packages. All devices are offered in standard pin
configurations and operate over the extended temperature
range of -40°C to +125°C.

... Single Channel Usage The ISL28218 is a dual op amp. If the application requires only one channel, the user must configure the unused channel to prevent it from oscillating. The unused channel oscillates if the input and output pins are floating. This results in higher-than-expected supply currents and possible noise injection into the channel being used ...
