ACPL-C78A, ACPL-C780, ACPL-C784  
Miniature Isolation Amplifiers  
Data Sheet  
Description  
Features  
The ACPL-C78A/C780/C784 family of isolation ampli- • 15 kV/μs Common-Mode Rejection at V = 1000 V  
CM  
fiers is designed for current sensing in electronic motor  
drives. In a typical implementation, motor currents flow  
through an external resistor and the resulting analog  
• Compact, Auto-Insertable Stretched SO-8 Package  
• 0.00025 V/V/°C Gain Drift vs. Temperature  
voltage drop is sensed by the ACPL-C78A/C780/C784. A  
differential output voltage is created on the other side of  
the ACPL-C78A/C780/C784 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 ap-  
plication circuit. Since common-mode voltage swings  
of several hundred volts in tens of nanoseconds are  
common in modern switching inverter motor drives, the  
ACPL-C78A/C780/C784 is designed to ignore very high  
common-mode transient slew rates (of at least 10 kV/μs).  
• 0.± mV Input Offset Voltage  
• 100 kHz Bandwidth  
• 0.0043 Nonlinearity  
• WorldwideSafetyApproval:UL1577(5000Vrms/1min.),  
CSA and IEC/EN/DIN EN 60747-5-5  
• Advanced Sigma-Delta (∑-∆) A/D Converter Technology  
• Fully Differential Amplifier  
Applications  
• Motor Phase and Rail Current Sensing  
• Inverter Current Sensing  
The high CMR capability of the ACPL-C78A/C780/C784  
isolation amplifier provides the precision and stability  
needed to accurately monitor motor current in high noise  
motor control environments, providing for smoother  
control (less “torque ripple”) in various types of motor  
control applications.  
• DC bus voltage sensing  
• General Purpose Current Sensing and Monitoring  
• General Purpose Analog Signal Isolation  
The product can also be used for general analog signal  
isolation applications requiring high accuracy, stability,  
and linearity under similarly severe noise conditions. For  
general applications, we recommend the ACPL-C780 (gain  
tolerance of ±±3) and the ACPL-C784 (gain tolerance of  
±53). For precision applications AvagoTechnologies offers  
the ACPL-C78A with part-to-part gain tolerance of ±13.  
The ACPL-C78A/C780/C784 utilizes sigma-delta (∑-∆) an-  
alog-to-digital converter technology, chopper stabilized  
amplifiers, and a fully differential circuit topology.

SHIELD  
Together, these features deliver unequaled isolation-  
mode noise rejection, as well as excellent offset and gain  
accuracy and stability over time and temperature. This  
performance is delivered in a compact, auto-insertable,  
Stretched SO-8 (SSO-8) package that meets worldwide  
regulatory safety standards.  
NOTE: A 0.1 μF 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.
