GENERAL DESCRIPTION

GND

(AD8802 ONLY)

REFL

(AD8804 ONLY)

The 12-channel AD8802/AD8804 provides independent digitally-

controllable voltage outputs in a compact 20-lead package. This

potentiometer divider TrimDAC® allows replacement of the

mechanical trimmer function in new designs. The AD8802/

AD8804 is ideal for dc voltage adjustment applications.

Each DAC has its own DAC latch that holds its output state.

These DAC latches are updated from an internal serial-to-

parallel shift register that is loaded from a standard 3-wire

serial input digital interface. The serial-data-input word is

decoded where the first 4 bits determine the address of the DAC

latches to be loaded with the last 8 bits of data. The AD8802/

AD8804 consumes only 10 µA from 5 V power supplies. In ad-

dition, in shutdown mode reference input current consumption

is also reduced to 10 µA while saving the DAC latch settings for

use after return to normal operation.

Easily programmed by serial interfaced microcontroller ports,

the AD8802 with its midscale preset is ideal for potentiometer

replacement where adjustments start at a nominal value. Appli-

cations such as gain control of video amplifiers, voltage con-

trolled frequencies and bandwidths in video equipment,

geometric correction and automatic adjustment in CRT com-

puter graphic displays are a few of the many applications ideally

suited for these parts. The AD8804 provides independent con-

trol of both the top and bottom end of the potentiometer divider

allowing a separate zero-scale voltage setting determined by the

V_REFLpin. This is helpful for maximizing the resolution of

devices with a limited allowable voltage control range.

The AD8802/AD8804 is available in the 20-pin plastic DIP, the

SOIC-20 surface mount package, and the 1 mm thin TSSOP-20

package.

Internally the AD8802/AD8804 contains 12 voltage-output

digital-to-analog converters, sharing a common reference-

voltage input.
