12-Bit, 20kSPS SAR ADC
ISL2671286
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 15W 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.
