Analog Isolation Amplifier  
Technical Data  
HCPL-7840  
Features  
Description  
environments such as those  
generated by the high switching  
rates of power IGBTs.  
• High Common Mode  
Rejection (CMR): 15 kV/µs  
at VCM = 1000V  
• 5% Gain Tolerance  
• 0.1% Nonlinearity  
• Low Offset Voltage and Off-  
set Temperature Coefficient  
• 100 kHz Bandwidth  
• Performance Specified Over  
-40°C to 85°C Temperature  
Range  
• Recognized Under UL 1577  
and CSA Approved for  
Dielectric Withstand Proof  
Test Voltage of 2500 Vac, 1  
Minute  
The HCPL-7840 isolation ampli-  
fier provides accurate, electrically  
isolated and amplified representa-  
tions of voltage and current.  
Low offset voltage together with  
a low offset voltage temperature  
coefficient permits accurate use  
of auto-calibration techniques.  
When used with a shunt resistor  
in the current path, the HCPL-  
7840 offers superior reliability,  
cost effectiveness, size and  
autoinsertability compared with  
the traditional solutions such as  
current transformers and Hall-  
effect sensors.  
Gain tolerance of 5% with 0.1%  
nonlinearity further provide the  
performance necessary for  
accurate feedback and control.  
A wide operating temperature  
range with specified performance  
allows the HCPL-7840 to be used  
in hostile industrial environments.  
The HCPL-7840 consists of a  
sigma-delta analog-to-digital  
converter optically coupled to a  
digital-to-analog converter.  
• Standard 8-Pin DIP Package  
Superior performance in design  
critical specifications such as  
common-mode rejection, offset  
voltage, nonlinearity, operating  
temperature range and regulatory  
compliance make the HCPL-7840  
the clear choice for designing  
reliable, lower-cost, reduced-size  
products such as motor

Signal Isolation  
Common-mode rejection of  
15 kV/µs makes the HCPL-7840  
suitable for noisy electrical  
A 0.1 F bypass capacitor must be connected between pins 1 and 4 and between pins 5 and 8.  
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.
