Product Summary

The ISO122JP is a precision isolation amplifier incorporating a novel duty cycle modulation-demodulation technique. The signal is transmitted digitally across a 2pF differential capacitive barrier. With digital modulation, the barrier characteristics of the ISO122JP do not affect signal integrity, resulting in excellent reliability and good high frequency transient immunity across the barrier. Both barrier capacitors are imbedded in the plastic body of the package. The applications of the ISO122JP include industrial process control: Transducer Isolator, Isolator for Thermo-couples, RTDs, Pressure Bridges, and Flow Meters, 4mA to 20mA Loop Isolation, ground loop elimination, motor and SCR Control, power monitoring, PC-based data acquisition and test equipment.
