Powerdown Mode
A powerdown mode can be selected with pin PDN. When
PDN = 1, the device is powered down. In this state, the power
consumption is reduced by removing power from the analog
section and forcing the analog output, VOUT, to a high
impedance state. While the device is in power down mode,
the digital section is still functional and the current data word
remains stored in the latch. The master clock, CLK, can
be left active or removed during powerdown mode. When
PDN = 0, the device is in normal operation.
Power Supplies
The digital section inside the device is powered between
VCC and GND, or 5 volts. The analog section is powered
between VCC and VSS, or ±5 volts. The analog section uses
AGND as the reference point.
GND and AGND are totally isolated inside the device to
minimize coupling from the digital section into the analog
section. Typically this is less than 100 V. However, ANGD
and GND should be tied together physically near the device
and close to the common power supply ground connection.
The power supply rejection of VCC and VSS to the analog
output is greater than –60dB at 1 kHz, typically. If decou-
pling of the power supplies is still necessary in a system,
VCC and VSS should be decoupled with respect to AGND.
