ACPL-C79B, ACPL-C79A, ACPL-C790  
Precision Miniature Isolation Amplifiers  
Data Sheet  
Description  
Features  
The ACPL-C79B/C79A/C790 isolation amplifiers are • ±0.ꢁ1 High Gain Accuracy (ACPL-C79B)  
designed for current and voltage sensing in electronic  
power converters in applications including motor drives  
and renewable energy systems. In a typical motor drive  
• –ꢁ0 ppm/°C Low Gain Drift  
• 0.6 mV Input Offset Voltage  
implementation, current flows through an external • 0.0ꢁ1 Excellent Linearity  
resistor and the resulting analog voltage drop is sensed by  
the isolation amplifier. A differential output voltage that is  
proportional to the current is created on the other side of  
• 60 dB SNR  
• 200 kHz Wide Bandwidth  
the optical isolation barrier.  
• ꢀ V to ꢁ.ꢁ V Wide Supply Range for Output Side  
• –40°C to +±0ꢁ°C Operating Temperature Range  
• Advanced Sigma-Delta (∑-∆) A/D Converter Technology  
• Fully Differential Isolation Amplifier  
For general applications, the ACPL-C79A (±±1 gain  
tolerance) and the ACPL-C790 (±ꢀ1 gain tolerance)  
are recommended. For high precision applications, the  
ACPL-C79B (±0.ꢁ1 gain tolerance) can be used. The  
product operates from a single ꢁ V supply and provides  
excellent linearity and dynamic performance of 60 dB SNR.  
With 200 kHz bandwidth, ±.6 µs fast response time, the  
product captures transients in short circuit and overload  
conditions. The high common-mode transient immunity  
(±ꢁ kV/µs) of the ACPL-C79B/C79A/C790 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.  
• ±ꢁ kV/µs Common-Mode Transient Immunity  
• Compact, Auto-Insertable Stretched SO-8 Package  
• Safety and Regulatory Approvals:  
– IEC/EN/DIN EN 60747-ꢁ-ꢁ: ±4±4 Vpeak working  
insulation voltage  
– UL ±ꢁ77: ꢁ000 Vrms/±min double protection rating  
– CSA: Component Acceptance Notice #ꢁ  
Applications  
• Current/Voltage Sensing in AC and Servo Motor Drives  
• Solar Inverters, Wind Turbine Inverters  
• Industrial Process Control  
Combined with superior optical coupling technology, the  
ACPL-C79B/C79A/C790 implements sigma-delta (∑-∆)  
analog-to-digital converter, chopper stabilized ampli-  
fiers, and a fully differential circuit topology to provide  
unequaled isolation-mode noise rejection, low offset,  
high gain accuracy and stability. This performance is  
delivered in a compact, auto-insertable Stretched SO-8  
(SSO-8) package that meets worldwide regulatory safety  
standards.  
• Data acquisition systems  
• Switching Power Supply Signal Isolation  
• General Purpose Analog Signal Isolation  
• Traditional Current Transducer Replacements
