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.


  • Single or dual supply operation: ±1.35V to ±20V or 2.7V to 40V
  • Singled-ended or differential input operation with gain (G = 10V/V)
  • External VREF input
  • Banana jack connectors for power supply and VREF inputs
  • BNC connectors for op amp input and output terminals
  • Convenient PCB pads for op amp input/output impedance loading


  • Precision instruments
  • Active filter blocks
  • Data acquisition
  • Power supply control
  • Process control
