operation, but a differential input signal is required for best
performance.
Reference input. This pin should be bypassed to AGND with
a 0.1 µF monolithic capacitor. V
should be between 1.0V to 2.4V.
These pins are high impedance reference bypass pins.
Connect a 0.1 µF capacitor from each of these pins to AGND.
DO NOT LOAD these pins.
Digital clock input. The range of frequencies for this input is
100 kHz to 15 MHz (typical) with guaranteed performance at
10 MHz. The input is sampled on the rising edge of this input.
OE is the output enable pin that, when low, enables the
TRI-STATE
outputs are in a high impedance state.
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.
