Agilent HCPL-7860/HCPL-786J  
Optically Isolated  
Sigma-Delta (Σ−∆) Modulator  
Data Sheet  
In operation, the HCPL-7860/  
HCPL-786J Isolated Modulator  
Features  
12-bit Linearity  
(optocoupler with 3750 V  
RMS  
200 ns Conversion Time (Pre-  
dielectric withstand voltage  
rating) converts a low-  
Trigger Mode 2 with HCPL-0872)  
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 decoded  
into separate high-speed clock  
and data channels.  
12-bit Effective Resolution with 5  
µs Signal Delay (14-bit with 102  
µs) (with HCPL-0872)  
Description  
Fast 3 µs Over-Range Detection  
(with HCPL-0872)  
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.
