Design Notes

The AD7606BSTZ-RL requires a single 5 V analog supply (AVCC) and a separate digital supply (DVCC) that can range from 2.3 V to 5.25 V. Decouple AVCC with a 10 µF and 0.1 µF capacitor placed close to the pin. DVCC should be decoupled with a 0.1 µF capacitor. The VDRIVE pin sets the interface voltage level and should be connected to the host's I/O supply. Ensure that the power supplies are clean and stable to achieve the specified 16-bit performance.

For optimal performance, place the AD7606BSTZ-RL on a PCB with a solid ground plane. Separate analog and digital ground planes and connect them at a single point near the device. Keep analog input traces short and shielded to minimize noise pickup. Place the reference decoupling capacitor (REFCAP) close to the pin with a 10 µF and 0.1 µF capacitor. The analog inputs should be routed away from digital traces to avoid crosstalk.

A common mistake is not properly configuring the RANGE pin. The RANGE pin selects between ±5 V and ±10 V input ranges; leaving it floating may cause unpredictable behavior. Also, ensure that the CONVST A and CONVST B pins are connected together for simultaneous sampling of all 8 channels. The BUSY pin should be monitored to avoid reading data before conversion is complete. Additionally, the reference output (REFIN/REFOUT) must be decoupled with a 10 µF capacitor to maintain accuracy.
