Rad Hard 40V Quad Op Amp Evaluation Board
The ISL70444SEHEVAL1Z evaluation platform is designed to evaluate the ISL70444SEH 19MHz radiation hardened 40V quad rail-to-rail input-output (RRIO), low power...
Overview
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.
