Description
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 measurement of motor phase currents in power inverters. In operation, the HCPL-7860/HCPL-786J Isolated Modulator converts a low-bandwidth analog input into a highspeed 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.
