Conditions

Note

1: This parameter is ensured by design and not 100% tested.

2: This parameter is ensured by characterization and not 100% tested.

3: Decoupling capacitor is recommended on the following pins:

(a) AVDD pin: 1 F ceramic capacitor, (b) DVIO pin: 0.1 F ceramic capacitor, (c) VREF pin: 10 F tantalum capacitor.

4: PSRR (dB) = -20 log (DVOUT/AVDD), where DVOUT = change in conversion result.

5: ENOB = (SINAD - 1.76)/6.02
