Function
Power-Down Function Select; Logic HIGH for Power-Down Mode (Digital Outputs Go
to High Impedance State)
Internal Reference Output (1.25 V typ); Bypass with 0.1 µF to Ground
Reference Input for ADC (1.25 V typ)

Analog 3 V Power Supply
Analog Input for ADC (Can Be Left Open if Operating in Single-Ended Mode, but Rec-
ommend Connection to a 0.1 µF Capacitor and a 25 Ω Resistor in Series to Ground for
Better Input Matching)
Analog Input for ADC
