OPERATION
The AD8802/AD8804 provides twelve channels of program-
mable voltage output adjustment capability. Changing the pro-
grammed output voltage of each DAC is accomplished by
clocking in a 12-bit serial data word into the SDI (Serial Data
Input) pin. The format of this data word is four address bits,
MSB first, followed by 8 data bits, MSB first. Table I provides
the serial register data word format. The AD8802/AD8804 has
the following address assignments for the ADDR decode which
determines the location of the DAC register receiving the serial
register data in Bits B7 through B0:
DAC# = A3
× 8 + A2 × 4 + A1 × 2 + A0 + 1
DAC outputs can be changed one at a time in random se-
quence. The fast serial-data loading of 33 MHz makes it pos-
sible to load all 12 DACs in as little time as 4.6
µs (13
× 12 ×
30 ns). The exact timing requirements are shown in Figure 15.

The AD8802 offers a midscale preset activated by the RS pin
simplifying initial setting conditions at first power-up. The
AD8804 has both a VREFH and a VREFL pin to establish indepen-
dent positive full-scale and zero-scale settings to optimize reso-
lution. Both parts offer a power shutdown SHDN which places
the DAC structure in a zero power consumption state resulting
in only leakage currents being consumed from the power supply
and VREF inputs. In shutdown mode the DACX register settings
are maintained. When returning to operational mode from
power shutdown the DAC outputs return to their previous volt-
age settings.
