The ISL70444SEH 19MHz radiation hardened 40V quad rail-to-rail input-output (RRIO), low power operational amplifier contains four high-speed, low power op amps designed to take advantage of its full dynamic input and output voltage range with rail-to-rail operation. By offering low power, low offset voltage and low temperature drift coupled with its high bandwidth and enhanced slew rates upwards of 50V/μs, these op amps make it ideal for applications requiring both high DC accuracy and AC performance. This 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.
