Key Differentiators
- Higher data rate than ISO7761DW (vs ISO7761DW)
- Higher isolation voltage than SI8661BB-B-IS1 (vs SI8661BB-B-IS1)
- Wider supply voltage range than ISO7761DW (vs ISO7761DW)
Design Notes
For optimal isolation performance, maintain proper creepage and clearance distances on the PCB. The wide SOIC-16 package provides 8mm creepage, but ensure the PCB layout also maintains at least 8mm spacing between the isolated grounds. Use a solid ground plane under the device to reduce noise coupling.
Place 0.1Β΅F bypass capacitors close to each VDD pin (VDD1 and VDD2) to decouple high-frequency noise. Additionally, use a 10Β΅F bulk capacitor on each supply rail if the power source is far from the device. This ensures stable operation and reduces supply-induced jitter.
Do not exceed the absolute maximum ratings for supply voltage (7V) or input/output voltages. Ensure that the input signals do not exceed the supply voltage by more than 0.3V. Also, avoid floating unused inputs; tie them to GND or VDD as appropriate to prevent undefined states.
Compliance Information
RoHS compliant per Analog Devices product page. Other compliance data not specified in provided data.
