Optically Isolated Sigma-Delta Modulator
The HCPL-7560 Sigma-Delta Modulator optically Isolated Modulator and HCPL-0872 Digital Interface IC or digital filter together form a optocoupler isolated programmable two-chip analog-to-digital converter. The isolated Sigma-Delta Modulator allows direct measurement of motor phase currents in power inverters.
In operation, the HCPL-7560 Sigma-Delta isolated Modulator (optocoupler with 3750 Vrms dielectric withstand voltage rating) converts a low-bandwidth analog input into a high-speed one-bit data stream by means of a Sigma-Delta isolated over-sampling modulator. This modulation provides for high noise margins and excellent immunity against isolation-mode transients. The sigma-delta 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.
