- Cross-brand alternative ADS8588S has 8 channels (vs ADS8588S)
Design Notes
The AD7606BSTZ-4 requires a clean 5 V analog supply (AVCC) and digital supply (DVCC). Decouple each supply pin with a 10 µF and 0.1 µF capacitor placed as close to the pins as possible. The internal reference buffer requires a 1 µF capacitor on the REFCAP pin. Ensure the analog and digital grounds are connected at a single point to minimize noise.
For optimal performance, use a solid ground plane and separate analog and digital ground planes if possible. Route analog inputs away from digital traces to avoid coupling. The 64-LQFP package has an exposed pad that should be soldered to the ground plane for thermal and electrical performance. Place the decoupling capacitors on the same layer as the IC to minimize inductance.
Do not exceed the absolute maximum input voltage of ±16.5 V on the analog inputs, as the clamp protection is not a substitute for proper input conditioning. Ensure the input signals are within the selected range (±10 V or ±5 V) to avoid clipping. The oversampling pins (OS0-OS2) must be set correctly to achieve the desired SNR and throughput; leaving them floating can cause unpredictable behavior. Always reset the device after power-up to ensure proper initialization.
