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.

The serial digital interface is SPI compatible and is easily

interfaced to all popular FPGAs and microcontrollers.

Operating from a 5V supply, power dissipation is 1.4mW at a

sampling rate of 20kSPS and just 15μW between conversions

utilizing the Auto Power-Down mode. These features make the

ISL2671286 an excellent solution for remote industrial

sensors and battery-powered instruments.

The ISL2671286 is available in an 8 Ld SOIC package and is

specified for operation over the industrial temperature range

of –40°C to +85°C.
