DATASHEET  
ISL267817  
12-Bit Differential Input 200kSPS SAR ADC  
FN7877  
Rev 2.00  
April 19, 2012  
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  
Features  
• Drop-In Compatible with ADS7817 (All Performance Grades)  
• Differential Input  
• Simple SPI-compatible Serial Digital Interface  
• Guaranteed No Missing Codes  
maintained with input signals up to the supply rails.  
• 200kHz Sampling Rate  
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.  
• +4.75V to +5.25V Supply  
• Low 2.15mW Operating Power (200kSPS)  
• Power-down Current between Conversions: 3µA  
• Excellent Differential Non-Linearity (1.0LSB max)  
• Low THD: -85dB (typ)  
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 25µW 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).  
• Pb-Free (RoHS Compliant)  
• Available in SOIC and MSOP Packages  
Applications  
• Remote Data Acquisition  
• Battery Operated Systems  
• Industrial Process Control  
• Energy Measurement  
• Data Acquisition Systems  
• Pressure Sensors  
• Flow Controllers
