Overview: DATASHEET ISL70444SEH, ISL73444SEH
19MHz Radiation Hardened 40V Quad Rail-to-Rail Input - Output, Low-Power Operational Amplifiers The ISL70444SEH and ISL73444SEH (ISL7x444SEH) feature four low-power amplifiers optimized to provide maximum dynamic range. These operational amplifiers (op amps) feature a unique bination 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 ISL7x444SEH also offer low power, low offset voltage, and low temperature drift, making them 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 ponents needed is drastically reduced. The ISL7x444SEH are also immune to single event latch-up because they are fabricated using 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 ISL7x444SEH are available in a 14 Ld hermetic ceramic flatpack and die forms that operate across the temperature range of -55°C to +125°C.
