DATASHEET  
ISL2671286  
12-Bit, 20kSPS SAR ADC  
FN7863  
Rev 0.00  
November 1, 2011  
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.  
Features  
• Drop-In Compatible with ADS1286 (All Performance Grades)  
• Simple SPI-compatible Serial Digital Interface  
• Guaranteed No Missing Codes  
• 20kHz Sampling Rate  
• +4.50V to +5.25V Supply  
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.  
• Low 280µA Operating Current (20kSPS)  
• Power-down Current between Conversions: 3µA  
• Excellent Differential Non-Linearity (0.75LSB Max)  
• Low THD: -83dB (Typ)  
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.  
• Pb-Free (RoHS Compliant)  
• Available in SOIC Package  
Applications  
• Remote Data Acquisition  
• Battery Operated Systems  
• Industrial Process Control  
• Energy Measurement  
• Data Acquisition Systems  
• Pressure Sensors  
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.  
• Flow Controllers
