V or 3.3-V logic level can be used.

VCA partial (fast) power down control pin with an internal pull down resistor of 20 k

Ω. Active High. 3.3-V logic

PDN_VCA

level is recommended.

Global (complete) power-down control pin for the entire chip with an internal pull down resistor of 20 k

Ω. Active

PDN_GLOBAL

High. 3.3-V logic level is recommended.

0.5-V reference output in the internal reference mode. Must leave floated in the internal reference mode.
