The ISO120 and ISO121 are precision isolation amplifiers
incorporating a novel duty cycle modulationdemodulation
technique. The signal is transmitted
digitally across a 2pF differential capacitive barrier.
With digital modulation the barrier characteristics do
not affect signal integrity, which results in excellent
reliability and good high frequency transient immunity
across the barrier. Both the amplifier and barrier
capacitors are housed in a hermetic DIP. The ISO120
and ISO121 differ
