Overview
Description
The ISL70244SEH features two 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 the ISL70244SEH 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 ISL70244SEH is also immune to single-event latch-up because it is fabricated in the Renesas proprietary PR40 Silicon On Insulator (SOI) process. 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. The ISL70244SEH is available in a 10 Ld hermetic ceramic flatpack that operates across the temperature range of -55 °C to +125 °C.
