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 VREF determines the full-scale
output voltage. Valid VREF values include VSS<VREF<VDD resulting
in a wide selection of full scale outputs. For multiplying
applications AC inputs can be as large as |VDD-VSS|. Two on-board
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.

NOTES:
1. DAC Output Equation: VOUT = VREFL + [(VREFH-VREFL)*Code/2^N], where Code = data loaded in corresponding DAC register A, B, C, D and N equals the
DAC resolution AD5582 = 12, AD5583 = 10 bits. One LSB = VREF/4096V for the 12-bit AD5582.
2. The first two codes (000H, 001H) are excluded from the linearity error measurement in single supply operation.
3. These parameters are guaranteed by design and not subject to production testing.
4. When VREF is connected to either the VDD or the VSS power supply the corresponding VOUT voltage will program between ground and the supply voltage
minus the offset voltage of the output buffer, which is the same as the VZSE error specification. See additional discussion in the operation section of the data
sheet.
5. Typical specifications represent average readings measured at 25°C.
6. The settling time specification does not apply for negative going transitions within the last 3 LSBs of ground in single supply operation.
This information applies to a product under development. Its characteristics and specifications are subject to change without notice. Analog Devices assumes no obligation regarding future
manufacture unless otherwise agreed to in writing.
