DescriptionThe HCPL-7860/HCPL-786J Optically Isolated Modulator and HCPL-0872 Digital Interface IC or digital filter together form an isolated programmable two-chip analog-to-digital converter. The isolated modulator allows direct measurement of motor phase currents in power inverters.
In operation, the HCPL-7860/HCPL-786J Isolated Modulator (optocoupler with 3750 VRMS dielectric withstand voltage rating) converts a lowbandwidth analog input into a high-speed one-bit data stream by means of a Sigma-Delta (−?) over-sampling modulator.
This modulation of HCPL-7860/HCPL-786J provides for high noise margins and excellent immunity against isolation-mode transients. The modulator data and on-chip sampling clock are encoded and transmitted across the isolation boundary where they are recovered and decoded into separate high-speed clock and data channels.
