12-Bit, 20kSPS SAR ADC

The ISL2671286 is a sampling SAR-type ADC which features excellent linearity over supply and temperature variations, and provides a drop-in compatible alternative to all ADS1286 performance grades. The robust high impedance input minimizes errors due to leakage currents, and specified measurement accuracy is maintained with input signals up to the supply rails.
The reference accepts inputs between 1.25V to 5.0V, providing design flexibility in a wide variety of applications. The ISL2671286 also features up to 8kV Human Body Model ESD survivability.
