Design Notes
The AD7606BSTZ-4 requires a clean 5 V analog supply (AVCC) and digital supply (DVCC). Use separate analog and digital ground planes to minimize noise coupling. Place 0.1 µF and 10 µF decoupling capacitors close to each supply pin. The VDRIVE pin should be connected to the host interface voltage (e.g., 3.3 V or 5 V) to ensure proper logic levels. Ensure adequate power supply rejection by using low-noise LDOs if the input supply is noisy.
For optimal performance, route analog inputs away from digital traces and use a solid ground plane under the device. Keep the analog input traces short and shielded if possible. The REFCAP pin requires a 10 µF low-ESR ceramic capacitor to ground for stable reference operation. Place the capacitor as close to the pin as possible. The antialiasing filter is integrated, but external RC filtering may be added for very noisy environments. Ensure the exposed pad (if present) is soldered to the ground plane for thermal and electrical performance.
A common mistake is exceeding the absolute maximum input voltage. The AD7606BSTZ-4 has input clamp protection up to ±16.5 V, but sustained voltages beyond this can damage the device. Ensure input signals are within the specified ±10 V or ±5 V ranges. Another pitfall is incorrect configuration of the PAR/SER pin; if set to parallel mode, the serial interface pins are disabled. Also, the CONVST_A and CONVST_B pins must be triggered correctly for simultaneous sampling; in 4-channel mode, CONVST_B is unused but should be tied to a defined level. Finally, do not forget to connect the RESET pin properly; a power-on reset pulse is recommended.
