Design Notes
Decouple the AVCC and DVCC supplies with 10 µF and 0.1 µF capacitors placed as close to the pins as possible. Use separate analog and digital ground planes to minimize noise coupling. The AD7606BSTZ operates from a single 5V supply; ensure the supply is clean and well-regulated to achieve specified performance.
Place the REFIN/REFOUT and REFCAP decoupling capacitors close to the pins. Use a 1 µF capacitor on REFCAP and a 10 µF capacitor on REFIN/REFOUT. The analog input traces should be kept short and shielded to reduce noise pickup. Follow the layout guidelines in the AD7606 datasheet for optimal performance.
Ensure the CONVST A and CONVST B pins are driven simultaneously to achieve true simultaneous sampling. If using the internal reference, do not load the REFIN/REFOUT pin with excessive capacitance. The digital filter can be used to reduce noise, but it increases conversion time. Verify the input voltage range setting (RANGE pin) matches your signal levels.
