Product Summary
The ISO124P is a precision isolation amplifier incor-porating a novel duty cycle modulation-demodulation technique. The signal is transmitted digitally acrossa 2pF differential capacitive barrier. With digital modu-lation the barrier characteristics do not affect signalintegrity, resulting in excellent reliability and good highfrequency transient immunity across the barrier. Both barrier capacitors are imbedded in the plastic body ofthe package.The ISO124P is easy to use. No external componentsare required for operation. The key specifications are0.010% max nonlinearity, 50kHz signal bandwidth,and 200 μV/℃ VOS drift. A power supply range of±4.5V to ±18V and quiescent currents of ±5.0mA on VS1 and ±5.5mA on VS2 make these amplifiers idealfor a wide range of applications.The ISO124P is available in 16-pin plastic DIP and 28-lead plastic surface mount packages.
