The ISL28286 and ISL28486 are Dual and Quad channel micropower precision operational amplifiers optimized for single supply operation at 5V down to 2.4V.
The ISL28286 (dual‑channel) and ISL28486 (quad‑channel) are micropower precision operational amplifiers optimized for single‑supply operation from 5 V down to 2.4 V. They feature an Input Range Enhancement Circuit that maintains CMRR performance up to the supply rails, allowing the input to swing 10 % above the positive rail and down to ground. Both devices draw minimal supply current while delivering low offset, low noise, and rail‑to‑rail output swing.
Typical applications include battery‑ or solar‑powered systems, handheld consumer products, medical devices, thermocouple amplifiers, photodiode pre‑amps, and pH‑probe amplifiers. Ordering information, package dimensions (MSOP and QSOP), pinouts, absolute maximum ratings, and extensive performance curves are provided in the datasheet.
| Typical Supply Current (enabled, all channels) | 120 µA |
|---|---|
