Design Notes
For optimal isolation performance, maintain a clean separation between the input and output ground planes. Use a slot or cutout under the device to increase creepage distance. Place decoupling capacitors close to the VDD1 and VDD2 pins, typically 0.1uF and 10uF. Follow the layout guidelines in the datasheet to achieve the specified common-mode transient immunity.
Ensure that the supply voltages for the input and output sides are within the recommended operating range. Use low-ESR capacitors for decoupling to minimize noise. The device's power consumption is low, but proper bypassing is essential for stable operation. Refer to the datasheet for the recommended supply voltage and current requirements.
Do not exceed the absolute maximum ratings for supply voltage or input voltage. The gain setting pin must be connected correctly to achieve the desired gain. Avoid floating unused pins; connect them to ground or leave as per datasheet. Ensure that the isolation barrier is not compromised by PCB traces or vias that cross the isolation boundary.
