GENERAL DESCRIPTION
The AD5582/AD5583 family of quad, 12-/10-bit, voltage-output
digital-to-analog converter is designed to operate from a single +5
to +15 volt or a dual ±5V supply. Built using a CBCMOS process,
this monolithic DAC offers the user low cost, and ease-of-use in
single or dual-supply systems.
The applied external reference V
output voltage. Valid V
values include VSS<V
REF
determines the full-scale
REF
REF<VDD
resulting
in a wide selection of full scale outputs. For multiplying
applications AC inputs can be as large as |V
|. Two on-board
DD-VSS
precision trimmed resistors are available for 4-Quadrant
configurations.
A doubled-buffered parallel interface offers 25Mbps data load rates.
A common level-sensitive load-DAC strobe (LDAC) input allows
simultaneous update of all DAC outputs from previously loaded
Input Registers. An external asynchronous reset (RS) forces all
registers to the zero code state when MSB='0' or to midscale when
MSB='1'.
Both parts are offered in the same pin-out to allow users to select
the amount of resolution appropriate for their application without
circuit card redesign.
The AD5582/AD5583 are specified over the extended industrial
(-40°C to +125°C) temperature range. Packages available include
thin 1.1 mm TSSOP-48 package.
