ACPL-796J  
Optically Isolated Sigma-Delta Modulator  
Data Sheet  
Description  
Features  
The ACPL-796J is a 1-bit, second-order sigma-delta (ꢀꢁꢂ)  
modulator converts an analog input signal into a high-  
speed data stream with galvanic isolation based on optical  
coupling technology. The ACPL-796J operates from a 5 V  
power supply with dynamic range of 80 dB with an appro-  
priate digital filter. The differential inputs of ±±00 mV (full  
scale ±ꢀ±0 mV) are ideal for direct connection to shunt  
resistors or other low-level signal sources in applications  
such as motor phase current measurement.  
5 MHz to ±0 MHz external clock input range  
1-bit, second-order sigma-delta modulator  
16 bits resolution no missing codes (1± bits ENOB)  
74 dB minimum SNR  
ꢀ.5 V/°C maximum offset drift  
±1ꢁ maximum gain error  
Internal reference voltage  
±±00 mV linear range with single 5 V supply  
ꢀ V to 5.5 V wide supply range for digital interface  
–40°C to +105°C operating temperature range  
SO-16 package  
The analog input is continuously sampled by means of  
sigma-delta over-sampling using external clock, coupled  
across the isolation barrier, which allows synchronous  
operation with any digital controller. The signal infor-  
mation is contained in the modulator data, as a density  
of ones with data rate up to ±0 MHz, and the data are  
encoded and transmitted across the isolation boundary  
where they are recovered and decoded into high-speed  
data stream of digital ones and zeros. The original signal  
information can be reconstructed with a digital filter. The  
serial interface has a wide supply range of ꢀ V to 5.5 V.  
±5 kV/s common-mode transient immunity  
Safety and regulatory approval (pending):  
IEC/EN/DIN EN 60747-5-5: 1±ꢀ0 Vpeak working  
insulation voltage  
UL 1577: 5000 Vrms/1min double protection rating  
CSA: Component Acceptance Notice #5  
Applications  
Combined with superior optical coupling technology,  
the modulator delivers high noise margins and excellent  
immunity against isolation-mode transients. With 0.5 mm  
minimum distance through insulation (DTI), the ACPL-796J  
provides reliable double protection and high working  
insulation voltage, which is suitable for fail-safe designs.  
This outstanding isolation performance is superior to  
alternatives including devices based on capacitive- or  
magnetic-coupling with DTI in micro-meter range. Offered  
in an SO-16 package, the isolated ADC delivers the reli-  
ability, small size, superior isolation and over-temperature  
performance motor drive designers need to accurately  
measure current at much lower price compared to tradi-  
tional current transducers.
