Key Differentiators
- Lowest power consumption in AD7766 family (vs AD7766BRUZ)
- Higher dynamic range than AD7766-1BRUZ (vs AD7766-1BRUZ)
- Lower output data rate for lower power (vs AD7766-1BRUZ)
Design Notes
The AD7766-2BRUZ operates from a 2.5 V supply. Use a low-noise LDO regulator to provide a clean supply voltage, and place a 10 Β΅F ceramic capacitor and a 0.1 Β΅F capacitor close to the VDD pin. This ensures stable operation and minimizes noise coupling into the ADC.
For optimal performance, keep the analog input trace short and shield it from digital signals. Use a ground plane under the ADC and avoid routing digital lines near the analog input. Place the reference bypass capacitor (10 Β΅F) close to the VREF pin to maintain reference stability.
Ensure the analog input is driven by a low-impedance source to avoid settling time errors. The reference input must be bypassed with a low-ESR capacitor to prevent noise. Also, avoid exceeding the absolute maximum ratings on the supply and input pins to prevent damage.
