Overview
Description
The ISL267817 is a 12-bit, 200kSPS sampling SAR-type ADC which features excellent linearity over supply and temperature variations, and provides a drop-in compatible alternative to all ADS7817 performance grades. The robust, fully-differential input offers high impedance to minimize errors due to leakage currents, and the specified measurement accuracy is maintained with input signals up to the supply rails.
