GENERAL D ESCRIP TIO N
T he high speed parallel data interface connects to the fastest
processors without wait states. T he 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. T he MSB bit can
be used to establish a preset to midscale when the reset input is
strobed.
T he 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. T he reference (VREF) is trimmed
to 2.5 volts output, and the on-chip amplifier gains up the DAC
output to 4.095 volts full scale. T he user needs only supply a +5
volt supply.
T he AD8582 is coded natural binary. T he 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.
T he 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 ± 5% power supply
range.

ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the AD8582 features proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high energy electrostatic discharges. T herefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.

REFERENCE
T he AD8582 is a complete, ready-to-use dual 12-bit digital-to-
analog converter. Only one +5 V power supply is necessary for
operation. It contains two voltage-switched, 12-bit, laser-
trimmed digital-to-analog converters, a curvature-corrected
bandgap reference, rail-to-rail output op amps, input registers,
and DAC registers. T he parallel data interface consists of twelve
data bits, DB0–DB11, an address select pin A/B, two load
strobe pins (LDA, LDB) and an active low CS strobe. In addi-
tion an asynchronous RST pin will set all DAC register bits to
zero causing the VOUT to become zero volts, or to midscale for
trimming applications when the MSB pin is programmed to
Logic 1. T his function is useful for power on reset or system
failure recovery to a known state.

Figure 3. Equivalent Schem atic of Analog Portion
T he internal DAC is a 12-bit voltage-mode device with an
output that swings from AGND potential to the 2.5 volt in-
ternal bandgap voltage. It uses a laser trimmed R-2R
ladder which is switched by N channel MOSFET s. T he out-
put voltage of the DAC has a constant resistance independent
of digital input code. T he DAC output (not available to the
user) is internally connected to the rail-to-rail output op amp.
O UTP UT SECTIO N
T he rail-to-rail output stage of this amplifier has been designed
to provide precision performance while operating near either
power supply. Figure 4 shows an equivalent output schematic of
the rail-to-rail amplifier with its N channel pull-down FET s that
will pull an output load directly to GND. T he output sourcing
current is provided by a P channel pull-up device that can sup-
ply GND terminated loads, especially important at the –5%
supply tolerance value of 4.75 volts.
AMP LIFIER SECTIO N
T he internal DAC’s output is buffered by a low power con-
sumption precision amplifier. T his low power amplifier contains
a differential PNP pair input stage which provides low offset
voltage and low noise, as well as the ability to amplify the zero-
scale DAC output voltages. T he rail-to-rail amplifier is config-
ured in a gain of 1.6384 (= 4.095 V/2.5 V) in order to set the
4.095 volt full-scale output (1 mV/LSB). See Figure 3 for an
equivalent circuit schematic of the analog section.

AD8582
Figures 5 and 6 in the typical performance characteristics sec-
tion provide information on output swing performance near
ground and full-scale as a function of load. In addition to resis-
tive load driving capability, the amplifier has also been carefully
designed and characterized for up to 500 pF capacitive load
driving capability.
One advantage of the rail-to-rail output amplifiers used in the
AD8582 is the wide range of usable supply voltage. T he part is
fully specified and tested over temperature for operation from
+4.75 V to +5.25 V. If reduced linearity and source current
capability near full scale can be tolerated, operation of the
AD8582 is possible down to +4.3 volts. T he minimum operat-
ing supply voltage versus load current plot, in Figure 1, pro-
vides information for operation below VDD = +4.75 V.
REFERENCE SECTIO N
T he internal 2.5 V curvature-corrected bandgap voltage refer-
ence is laser trimmed for both initial accuracy and low tempera-
ture coefficient. T he voltage generated by the reference is
available at the VREF pin. Since VREF is not intended to drive ex-
ternal loads, it must be buffered. T he equivalent emitter fol-
lower output circuit of the VREF pin is shown in Figure 3.
TIMING AND CO NTRO L
T he input registers are level triggered and acquire data from the
data bus during the time period when CS is low. T he input reg-
ister selected is determined by the A/B select pin, see T able I.
for a complete description. When CS goes high, the data is
latched into the register and held until CS returns low. T he
minimum time required for the data to be present on the bus
before CS returns high is called the data setup time (tDS) as seen
in T iming Diagram. T he data hold time (tDH) is the amount
of time that the data has to remain on the bus after CS goes
high. T he high speed timing offered by the AD8582 provides
for direct interface with no wait states in all but the fastest
microprocessors.
Bypassing the VREF pin will improve noise performance; how-
ever, bypassing is not required for proper operation. Figure 8
shows broadband noise performance.
P O WER SUP P LY
T he very low power consumption of the AD8582 is a direct re-
sult of a circuit design optimizing use of the CBCMOS process.
By using the low power characteristics of the CMOS for the
logic, and the low noise, tight matching of the complementary
bipolar transistors good analog accuracy is achieved.
T he data from the input registers is transferred to the DAC reg-
isters by the active low LDA and LDB pins. If these inputs are
tied together, a single logic input can perform a double buffer
update of the DAC registers, which in turn simultaneously
changes the analog output voltages to a new value. If the LDA
and LDB pins are wired low, they become transparent. In this
mode the input register data will directly control the output
voltages. Refer to the Control Logic T ruth T able for a com-
plete description.
For power-consumption sensitive applications it is important to
note that the internal power consumption of the AD8582 is
strongly dependent on the actual logic-input voltage levels
present on the DB0–DB11, CS, A/B, MSB, LDA, LDB and
RST pins. Since these inputs are standard CMOS logic struc-
tures they contribute static power dissipation dependent on the
actual driving logic VOH and VOL voltage levels. T he graph in
Figure 9 shows the effect on total AD8582 supply current as a
function of the actual value of input logic voltage. Conse-
quently, for optimum dissipation use of CMOS logic versus
Unipolar O utput O per ation
T his is the basic mode of operation for the AD8582. T he
AD8582 has been designed to drive loads as low as 820Ω in par-
allel with 500 pF. T he code table for this operation is shown in
T able II.
T T L provides minimal dissipation in the static state. A VINL
=
0 V on the DB0–11 pins provides the lowest standby dissipation
of 1 mA typical with a +5 V power supply.
As with any analog system, it is recommended that the AD8582
power supply be bypassed on the same PC card that contains
the chip. Figure 10 shows the power supply rejection versus fre-
quency performance. T his should be taken into account when
using higher frequency switched-mode power supplies with
ripple frequencies of 100 kHz and higher.
