DATASHEET  
ISL70444SEH, ISL73444SEH  
19MHz Radiation Hardened 40V Quad Rail-to-Rail Input - Output,  
Low-Power Operational Amplifiers  
FN8411  
Rev.8.1  
Apr 15, 2021  
The ISL70444SEH and ISL73444SEH (ISL7x444SEH) feature  
Features  
four low-power amplifiers optimized to provide maximum  
dynamic range. These operational amplifiers (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. The  
ISL7x444SEH also offer low power, low offset voltage, and low  
temperature drift, making them 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 ISL7x444SEH  
are also immune to single event latch-up because they are  
fabricated using the Renesas proprietary PR40 Silicon On  
Insulator (SOI) process.  
• Electrically screened to DLA SMD# 5962-13214  
• Acceptance tested to 50krad(Si) (LDR) wafer-by-wafer  
• <5µs recovery from SEE (LETTH = 86.4MeV•cm2/mg)  
• Unity gain stable  
• Rail-to-rail input and output  
• Wide gain·bandwidth product . . . . . . . . . . . . . . . . . . . . 19MHz  
• Wide single and dual supply range. . . . . . . . 2.7V to 40V max  
• Low input offset voltage . . . . . . . . . . . . . . . . . . . . . . . . . 400µV  
• Low current consumption (per amplifier) . . . . . . . 1.1mA, typ  
• No phase reversal with input overdrive  
• Slew rate  
- Large signal . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 60V/µs  
The amplifiers 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.  
• Operating temperature range. . . . . . . . . . . .-55°C to +125°C  
• ISL70444SEH radiation acceptance (see TID report)  
- High dose rate (50-300rad(Si)/s). . . . . . . . . . . 300krad(Si)  
- Low dose rate (0.01rad(Si)/s) . . . . . . . . . . . . . . .50krad(Si)  
• ISL73444SEH radiation acceptance (see TID report)  
- Low dose rate (0.01rad(Si)/s) . . . . . . . . . . . . . . .50krad(Si)  
• SEE hardness (see SEE report for details)  
The ISL7x444SEH are available in a 14 Ld hermetic ceramic  
flatpack and die forms that operate across the temperature  
range of -55°C to +125°C.  
- SEB LETTH (VS = ±21V). . . . . . . . . . . . . . 86.4MeV•cm2/mg
