Reference input. This pin should be bypassed to ground with
a 0.1 µF monolithic capacitor.
These pins are high impedance reference bypass pins only.
Connect a 0.1 µF capacitor from each of these pins to AGND.
DO NOT connect anything else to these pins.
Digital clock input. The input is sampled on the rising edge of
CLK.
OE is the output enable pin that, when low, enables the

PD is the Power Down input pin. When high, this input puts
the converter into the power down mode. When this pin is
low, the converter is in the active mode.
