5V Reference Supply. Bypass to GND with a 0.1µF capacitor as close to the pins as
possible. Note that noise performance of the device is dependent on the noise contribution
from the supply to V
together to share the same supply voltage if the supply for V
External Resistor. Connect a 7.5kΩ resistor to ground.
Power-Down Switch. Drive PD high to set the device in power-down mode. Drive PD low for
normal operation.
