Rad Hard Dual 36V Precision Single-Supply, Rail-to-Rail  
Output, Low-Power Operational Amplifiers  
ISL70218SRH  
Features  
The ISL70218SRH is a dual, low-power precision amplifier  
optimized for single-supply applications. This op amp features  
a common mode input voltage range extending to 0.5V below  
the V- rail, a rail-rail differential input voltage range, and  
rail-to-rail output voltage swing, which makes it ideal for  
single-supply applications where input operation at ground is  
important.  
• Wide Single and Dual Supply Range . . . . . . . .3V to 36V Max.  
• Low Current Consumption . . . . . . . . . . . . . . . . . . 850µA, Typ.  
• Low Input Offset Voltage. . . . . . . . . . . . . . . . . . . . . . 40µV, Typ.  
• Rail-to-Rail Output . . . . . . . . . . . . . . . . . . . . . . . . . . . . . <10mV  
• Rail-to-Rail Input Differential Voltage Range for Comparator  
Applications  
• Operating Temperature Range. . . . . . . . . . .-55°C to +125°C  
• Below-ground (V-) Input Capability to -0.5V.  
This op amp features low power, low offset voltage, and low  
temperature drift, making it ideal for applications requiring  
both high DC accuracy and AC performance. This amplifier is  
designed to operate over a single supply range of 3V to 36V or a  
split supply voltage range of +1.8V/-1.2V to ±18V. The  
combination of precision and small footprint provides the user  
with outstanding value and flexibility relative to similar  
competitive parts.  
• Low Noise Voltage . . . . . . . . . . . . . . . . . . . . . . 5.6nV/Hz, Typ.  
• Low Noise Current . . . . . . . . . . . . . . . . . . . . . .355fA/Hz, Typ.  
• Offset Voltage Temperature Drift. . . . . . . . . . . 0.3µV/°C, Typ.  
• No Phase Reversal  
• Radiation Tolerance  
Applications for this amplifier include precision  
instrumentation, data acquisition, precision power supply  
controls, and industrial controls.
