The 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 measure ment of motor phase currents in power inverters.
In operation, the HCPL-7860/HCPL-786J Isolated Modula tor converts a low-bandwidth analog input into a high speed one-bit data stream by means of a Sigma-Delta (Σ−∆) over-sampling modulator. This modulation 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 de coded into separate high-speed clock and data channels.
