GENERAL DESCRIPTION

The AD8582 is a complete, parallel input, dual 12-bit, voltage

output DAC designed to operate from a single +5 volt supply.

Built using a CBCMOS process, this monolithic DAC offers the

user low cost, and ease-of-use in +5 volt only systems.

Included on the chip, in addition to the DACs, are a rail-to-rail

amplifier, latch and reference. The reference (V

to 2.5 volts output, and the on-chip amplifier gains up the DAC

output to 4.095 volts full scale. The user needs only supply a +5

volt supply.

The AD8582 is coded natural binary. The op amp output

swings from 0 volt to +4.095 volts for a one-millivolt-per-bit

resolution, and is capable of driving 5 mA. Operation down to

4.3 V is possible with output load currents less than 1 mA.

The high speed parallel data interface connects to the fastest

processors without wait states. The double-buffered input struc-

ture allows the user to load the input registers one at a time,

then a single load strobe tied to both LDA + LDB inputs will

update both DAC outputs simultaneously. LDA and LDB can

also be activated independently to immediately update their re-

spective DAC registers. An address input decodes DAC A or

DAC B when the chip select CS input is strobed. An asynchro-

nous reset input sets the output to zero scale. The MSB bit can

be used to establish a preset to midscale when the reset input is

strobed.

The AD8582 is available in the 24-pin plastic DIP and the sur-

face mount SOIC-24. Each part is fully specified for operation

over –40 C to +85 C, and the full +5 V

range.
