GENERAL DESCRIPTION
The AD5582/AD5583 family of quad, 12-/10-bit, voltage output
digital-to-analog converters is designed to operate from a single
5 V to 15 V or dual ±5 V supply. It offers the user ease of use in
single- or dual-supply systems. Built using an advance BiCMOS
process, this high performance DAC is dynamically stable, capable
of high current drive, and in small form factor.
The applied external reference V_REF determines the full-scale out-
put voltage ranges from V_SS to V_DD, resulting in a wide selection
of full-scale outputs. For multiplying and wide dynamic appli-
cations, ac reference inputs can be as high as |V_DD – V_SS|. Two
built-in precision trimmed resistors are available and can be
configured easily to provide four-quadrant multiplications.
A doubled-buffered parallel interface offers a fast settling time.
A common level sensitive load DAC strobe (LDAC) input allows
additional simultaneous update of all DAC outputs. An external
asynchronous reset (RS) forces all registers to the zero code state
when the MSB = 0 or to midscale when the MSB = 1.
Both parts are offered in the same pinout and package to allow
users to select the appropriate resolution for a given application
without PCB layout changes.

The AD5582 is well suited for DAC8412 replacement in medium
voltage applications in new designs, as well as any other general
purpose multichannel 10- to 12-bit applications.
The AD5582/AD5583 are specified over the extended industrial
(–40∞C to +125∞C) temperature range and offered in a thin and
compact 1.1 mm TSSOP-48 package.
