The ISL70444SEH features four low-power amplifiers optimized to provide maximum dynamic range. This operational amplifier (op amps) features 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 ISL70444SEH also offers 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 because it is fabricated using the Renesas proprietary PR40 Silicon On Insulator (SOI) process. The amplifier is 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 this amplifier include precision instrumentation, data acquisition, precision power supply controls, and process controls. The ISL70444SEH are available in a 14 Ld hermetic ceramic flatpack and die forms that operate across the temperature range of -55°C to +125°C.
