19MHz Rad Hard 40V Quad Rail-to-Rail Input-Output,  
Low-Power Operational Amplifiers  
ISL70444SEH  
Features  
The ISL70444SEH features four low-power amplifiers  
optimized to provide maximum dynamic range. These op  
amps feature a unique combination of rail to rail operation on  
the input and output as well as a slew enhanced front end that  
provides ultra fast slew rates positively proportional to a given  
step size; thereby increasing accuracy under transient  
conditions, whether it’s periodic or momentary. They also offer  
low power, low offset voltage, and low temperature drift,  
making it ideal for applications requiring both high DC  
accuracy and AC performance. With <5µs recovery for Single  
Event Transients (SET) (LETTH = 86.4MeV•cm2/mg), the  
number of filtering components needed is drastically reduced.  
The ISL70444SEH is also immune to Single Event Latch-up as  
it is fabricated in Intersil’s Proprietary PR40 Silicon On  
Insulator (SOI) process.  
• Electrically screened to DLA SMD# 5962-13214  
• Acceptance tested to 50krad(Si) (LDR) wafer-by-wafer

• Operating temperature range. . . . . . . . . . . .-55°C to +125°C  
They are designed to operate over a single supply range of 2.7V  
to 40V or a split supply voltage range of ±1.35V to ±20V.  
Applications for these amplifiers include precision  
instrumentation, data acquisition, precision power supply  
controls, and process controls.

The ISL70444SEH is available in a 14 Ld Hermetic Ceramic  
Flatpack and die forms that operate over the temperature  
range of -55°C to +125°C.  
* Product capability established by initial characterization.
