When address bit4 = 1 and SEN has been pulsed high, this pin use as SDO for register data
read-back. Otherwise, this pin use as Digital Data Output.
P Analog Supply (3.3V).
AO Reference Decoupling, this pin must be connected to AGND via a decoupling capacitor.
AO Reference Decoupling, this pin must be connected to AGND via a decoupling capacitor.
AO Reference Decoupling, this pin must be connected to AGND via a decoupling capacitor.
Selectable analog output voltage for RLC or single-ended bias reference. This pin would typi-
AO cally be connected to AGND via a decoupling capacitor. VRLC can be externally driven if pro-
grammed Hi-z.
