The ISL28118, 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-to-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 SOIC and 8 Ld MSOP packages. All

devices are offered in standard pin configurations and operate

across the extended temperature range of -40°C to +125°C.
