OptoCoupler 8-Pin PDIP SMD T/R

The HCPL-7560 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-7560 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 SigmaDelta (S-?) 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 decoded into separate high-speed clock and data channels.
