The ISO120 and ISO121 are precision isolaTIon ampli-fiers incorporaTIng a novel duty cycle modulaTIon-demodulaTIon technique. The signal is transmitteddigitally across a 2pF differential capacitive barrier.With digital modulation the barrier characteristics donot affect signal integrity, which results in excellentreliability and good high frequency transient immu-nity across the barrier. Both the amplifier and barriercapacitors are housed in a hermetic DIP. The ISO120and ISO121 differ only in package size and isolationvoltage rating.These amplifiers are easy to use. No external compo-nents are required for 60kHz bandwidth. With theaddition of two external capacitors, precision specifi-cations of 0.01% max nonlinearity and 150µV/°C maxVOS drift are guaranteed with 6kHz bandwidth. Apower supply range of ±4.5V to ±18V and low quies-cent current make these amplifiers ideal for a widerange of applications.
