Product Summary

The ISO122P is a precision isolation amplifier incorporating a novel duty cycle modulation-demodulation technique. The signal of the ISO122P is transmitted digitally across a 2pF differential capacitive barrier. With digital modulation the barrier characteristics 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 ISO122P include ground loop elimination, motor and scr control, power monitoring, pc-based data acquisition and test equipment.
