40V Precision Single-Supply, Rail-to-Rail Output,  
Low-Power Operational Amplifiers  
ISL28118, ISL28218  
Features  
The ISL28118 and ISL28218 are single and dual, low-power  
precision amplifiers optimized for single-supply applications.  
These devices feature a common mode input voltage range  
extending to 0.5V below the V- rail, a rail-rail differential input  
voltage range for use as a comparator, and rail-to-rail output  
voltage swing, which makes them ideal for single-supply  
applications where input operation at ground is important.  
• Rail-to-Rail Output . . . . . . . . . . . . . . . . . . . . . . . . . . . . . <10mV  
• Below-Ground (V-) Input Capability to -0.5V  
• Rail-to-Rail Input Differential Voltage Range for Comparator  
Applications  
• Single-Supply Range . . . . . . . . . . . . . . . . . . . . . . . . . 3V to 40V  
• Low Current Consumption . . . . . . . . . . . . . . . . . . . . . . . 850µA  
• Low Noise Voltage . . . . . . . . . . . . . . . . . . . . . . . . . . 5.6nV/√Hz  
• Low Noise Current . . . . . . . . . . . . . . . . . . . . . . . . . . 355fA/√Hz  
These op amps feature low power, low offset voltage, and low  
temperature drift, making them the ideal choice for  
applications requiring both high DC accuracy and AC  
performance. These amplifiers are designed to operate over a  
single supply range of 3V to 40V or a split supply voltage range  
of +1.8V/-1.2V to ±20V. The combination of precision and  
small footprint provides the user with outstanding value and  
flexibility relative to similar competitive parts.  
• Low Input Offset Voltage  
- ISL28118 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 150µV Max.  
- ISL28218 . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 230µV Max.  
• Superb Offset Voltage Temperature Drift  
- ISL28118 . . . . . . . . . . . . . . . . . . . . . . . . . . . 1.2µV/°C, Max.  
- ISL28218 . . . . . . . . . . . . . . . . . . . . . . . . . . . 1.4µV/°C, Max.  
Applications for these amplifiers include precision  
instrumentation, data acquisition, precision power supply  
controls, and industrial controls.  
• Operating Temperature Range. . . . . . . . . . .-40°C to +125°C  
• No Phase Reversal  
Both parts are offered in 8 Ld TDFN, 8 Ld SOIC and 8 Ld MSOP  
packages. All devices are offered in standard pin  
configurations and operate over the extended temperature  
range of -40°C to +125°C.
