12-Bit Differential Input 200kSPS SAR ADC
ISL267817
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.
The reference accepts inputs between 0.1V to 2.5V, providing
design flexibility in a wide variety of applications. The
ISL267817 also features up to 8kV Human Body Model ESD
survivability.
The serial digital interface is SPI compatible and is easily
interfaced to popular FPGAs and microcontrollers. Operating
from a 5V supply, power dissipation is 2.15mW at a sampling
rate of 200kSPS, and just 25W between conversions utilizing
the Auto Power-Down mode, making the ISL267817 an
excellent solution for remote industrial sensors and
battery-powered instruments. It is available in the compact,
industry-standard 8 Lead SOIC and MSOP packages and is
specified for operation over the industrial temperature range
(-40°C to +85°C).
