The ISL70218SEH, ISL70218SRH are dual, low-power  
Features  
precision amplifiers optimized for single-supply applications.  
• DLA SMD# 5962-12222 (ISL70218SEH Only)  
These op amps feature a common-mode input voltage range  
extending to 0.5V below the V- rail, a rail-to-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 42V, Abs. Max.  
• Low current consumption . . . . . . . . . . . . . . . . .850µA, typical  
• Low input offset voltage. . . . . . . . . . . . . . . . . . . . 40µV, typical  
• Rail-to-rail output . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . <10mV  
These op amps feature low-power, low-offset voltage and  
low-temperature drift, making it ideal for applications  
requiring both high DC accuracy and AC performance. They are  
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.  
• 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  
• Low noise voltage . . . . . . . . . . . . . . . . . . . . 5.6nV/Hz, typical  
• Low noise current. . . . . . . . . . . . . . . . . . . . 355fA/Hz, typical  
Applications for these amplifiers include precision  
instrumentation, data acquisition and precision power supply  
controls.  
• Offset voltage temperature drift . . . . . . . . .0.3µV/°C, typical  
• No phase reversal  
• Radiation acceptance testing - ISL70218SRH  
- HDR (50-300rad(Si)/s) . . . . . . . . . . . . . . . . . . . 100krad(Si)  
• Radiation acceptance testing - ISL70218SEH  
- HDR (50-300rad(Si)/s) . . . . . . . . . . . . . . . . . . . 100krad(Si)  
- LDR (0.01rad(Si)/s) . . . . . . . . . . . . . . . . . . . . . . . .50krad(Si)  
• SEE hardness (see SEE report for details)  
ISL70218SEH, ISL70218SRH are available in a 10 lead  
hermetic ceramic flatpack and operate across the extended  
temperature range of -55°C to +125°C.  
Applications  
• Precision instruments  
• Active filter blocks  
• Data acquisition  
- SEB LETTH (VS = ±18V) . . . . . . . . . . . . . . 86.4MeV•cm2/mg  
- SEL Immune (SOI Process)  
• Power supply control
