HCPL-7560
Optically Isolated Sigma-Delta (Σ-∆) Modulator
Data Sheet
Description
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 mea-
surement of motor phase currents in power inverters.
In operation, the HCPL-7560 Isolated Modulator (op-
tocoupler with 3750 V
rating) 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 transmit-
ted across the isolation boundary where they are recov-
ered and decoded into separate high-speed clock and
data channels.
NOTE: A 0.1 μF bypass capacitor must be connected between pins VDD1 and GND1 and between pins VDD2 and GND2.
