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) (LET_TH = 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.

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 across the temperature range of -55°C to +125°C.
