Description
The ISL73444SEH features four low-power amplifiers optimized to provide maximum dynamic range. This operational amplifier (op amp) 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 ISL73444SEH 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 ISL73444SEH 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 ISL73444SEH is available in a 14 Ld hermetic ceramic flatpack and die forms that operate across the temperature range of -55 °C to +125 °C.

ISL70444SEH and ISL73444SEH Supply Sequencing Requirements
The power supplies should come up and be present before applying signals to the inputs of the op-amps. There is no maximum time limit to when one supply is present before the other is applied. Normally they should come up with minimal time between them. The order of which ...
