Description  
Functional Diagram  
The HCPL-7800(A) isolation  
amplifier family was designed  
for current sensing in electronic  
motor drives. In a typical

resistor and the resulting analog  
voltage drop is sensed by the  
HCPL-7800(A). A differential  
output voltage is created on the  
other side of the HCPL-7800(A)  
optical isolation barrier. This  
differential output voltage is  
proportional to the motor current  
and can be converted to a single-  
ended signal by using an op-amp  
as shown in the recommended  
application circuit. Since  
common-mode voltage swings of  
several hundred volts in tens of  
nanoseconds are common in  
modern switching inverter motor  
drives, the HCPL-7800(A)

accuracy, stability, and linearity  
under similarly severe noise con-  
ditions. For general applications,  
we recommend the HCPL-7800  
(gain tolerance of ± 3%). For  
precision applications Agilent  
offers the HCPL-7800A with part-  
to-part gain tolerance of ± 1%.  
The HCPL-7800(A) utilizes sigma  
delta (∑-∆) analog-to-digital  
was designed to ignore very high  
common-mode transient slew  
rates (of at least 10 kV/µs).  
The high CMR capability of the  
HCPL-7800(A) isolation amplifier  
provides the precision and  
stability needed to accurately  
monitor motor current in high  
converter technology, chopper  
stabilized amplifiers, and a fully  
differential circuit topology.  
CAUTION: It is advised that normal static precautions be taken in handling and assembly of this component to  
prevent damage and/or degradation which may be induced by ESD.
