Low-Cost, High-Voltage, Internally Powered Output Isolation Amplifiers，，

Instructions for Use:

1. Power Supply:

   • Ensure that both VDD1 and VDD2 are powered within the specified range (3.0 V to 5.5 V).
   • Use appropriate decoupling capacitors (typically 0.1 μF) close to each supply pin to minimize noise.

2. Signal Connections:

   • Connect the input signals to the primary side (VDD1 side) of the isolator.
   • Connect the output signals to the secondary side (VDD2 side) of the isolator.
   • Ensure signal levels are within the logic high and low thresholds of the device.

3. Grounding:

   • Connect the ground pins (GND1 and GND2) to the respective ground planes on the primary and secondary sides.
   • Maintain a clean and separate ground plane for each side to avoid ground loops.

4. Layout Considerations:

   • Place the ISO113 as close as possible to the source and load to minimize trace lengths.
   • Use wide and short traces for power and ground connections to reduce inductance and resistance.
   • Avoid routing high-speed or noisy signals near the isolation barrier to prevent crosstalk.

5. Thermal Management:

   • Ensure adequate heat dissipation by providing a thermal path to the PCB or heatsink if operating at high data rates or in high ambient temperatures.
   • Follow the recommended PCB layout guidelines provided in the datasheet for optimal thermal performance.

6. Safety and Compliance:

   • Ensure that the design meets all safety standards and regulations, particularly those related to isolation and electrical safety.
   • Refer to the safety certifications and compliance information provided in the datasheet to ensure proper usage.

7. Testing:

   • Verify the functionality of the isolator using a known good test setup before integrating it into the final application.
   • Perform functional tests at the minimum and maximum supply voltages and temperatures to ensure reliable operation.
