Design Notes

The AD6705 operates from a single supply, simplifying power design. Ensure adequate decoupling with a 0.1uF ceramic capacitor close to the supply pin and a 10uF bulk capacitor. The supply voltage range is not specified in the available data; refer to the AD670S datasheet for exact limits.

For optimal performance, keep analog input traces short and shielded from digital noise. Use a ground plane and separate analog and digital grounds if possible. The integrated signal conditioning reduces external component count, but careful layout of the input path is critical to maintain signal integrity.

Do not exceed the absolute maximum ratings specified in the datasheet. Ensure the input signal is within the common-mode range of the instrumentation amplifier. The device is aerospace-grade, so handle with ESD precautions. Verify the exact package and pinout from the AD670S datasheet before PCB design.
