Normally, connected to AVSS with a 10µF electrolytic capacitor and a 0.1µF
ceramic capacitor.
This pin goes to “H” if analog input overflows.
“H”: Power up, “L”: Power down
“H” : 24bit I
“H” : Master Mode,
“L” Output in Master Mode at Power-down mode.
“L” Output in Master Mode at Power-down mode.
“L” Output at Power-down mode.
“H” : Enable, “L” : Disable
Normally, connected to AVSS with a 10µF electrolytic capacitor and a 0.1µF
ceramic capacitor.
