8-Bit, High Speed, Multiplying D/A Converter
(Universal Digital Logic Interface)
DAC08
scale trimming in most applications. Direct interface to all
popular logic families with full noise immunity is provided by
the high swing, adjustable threshold logic input.
FEATURES
Fast settling output current: 85 ns
Full-scale current prematched to ±1 LSB
Direct interface to TTL, CMOS, ECL, HTL, PMOS
Nonlinearity to 0.1% maximum over temperature range
High output impedance and compliance: −10 V to +18 V
Complementary current outputs
Wide range multiplying capability: 1 MHz bandwidth
Low FS current drift: ±10 ppm/°C
Wide power supply range: ±4.5 V to ±18 V
Low power consumption: 33 mW @ ±5 V
Low cost
High voltage compliance complementary current outputs are
provided, increasing versatility and enabling differential
operation to effectively double the peak-to-peak output swing.
In many applications, the outputs can be directly converted to
voltage without the need for an external op amp. All DAC08
series models guarantee full 8-bit monotonicity, and nonlinearities as tight as ±0.1% over the entire operating temperature
range are available. Device performance is essentially unchanged
over the ±4.5 V to ±18 V power supply range, with 33 mW
power consumption attainable at ±5 V supplies.
GENERAL DESCRIPTION
The compact size and low power consumption make the DAC08
attractive for portable and military/aerospace applications;
devices processed to MIL-STD-883, Level B are available.
The DAC08 series of 8-bit monolithic digital-to-analog converters provide very high speed performance coupled with low cost
and outstanding applications flexibility.
DAC08 applications include 8-bit, 1 µs A/D converters, servo
motor and pen drivers, waveform generators, audio encoders
and attenuators, analog meter drivers, programmable power
supplies, LCD display drivers, high speed modems, and other
applications where low cost, high speed, and complete
input/output versatility are required.
Advanced circuit design achieves 85 ns settling times with very
low “glitch” energy and at low power consumption. Monotonic
multiplying performance is attained over a wide 20-to-1
reference current range. Matching to within 1 LSB between
reference and full-scale currents eliminates the need for full-

Stresses greater than those listed under Absolute Maximum
Ratings may cause permanent damage to the device. This is a
stress rating only and functional operation of the device at these
or any other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
ESD CAUTION
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 this product features
proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy
electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance
degradation or loss of functionality.

DAC08
APPLICATION INFORMATION
REFERENCE AMPLIFIER SETUP
The DAC08 is a multiplying D/A converter in which the output
current is the product of a digital number and the input
reference current. The reference current may be fixed or may
vary from nearly zero to 4.0 mA. The full-scale output current
is a linear function of the reference current and is given by
I FR =
255
× I REF
256
where IREF = I14
In positive reference applications, an external positive reference
voltage forces current through R14 into the VREF(+) terminal
(Pin 14) of the reference amplifier. Alternatively, a negative
reference may be applied to VREF(–) at Pin 15; reference current
flows from ground through R14 into VREF(+) as in the positive
reference case. This negative reference connection has the
advantage of a very high impedance presented at Pin 15. The
voltage at Pin 14 is equal to and tracks the voltage at Pin 15 due
to the high gain of the internal reference amplifier. R15 (nominally equal to R14) is used to cancel bias current errors; R15
may be eliminated with only a minor increase in error.
Bipolar references may be accommodated by offsetting VREF or
Pin 15. The negative common-mode range of the reference
amplifier is given by VCM – = V− plus (IREF × 1 kΩ) plus 2.5 V.
The positive common-mode range is V+ less 1.5 V.
When a dc reference is used, a reference bypass capacitor is
recommended. A 5.0 V TTL logic supply is not recommended
as a reference. If a regulated power supply is used as a reference,
R14 should be split into two resistors with the junction bypassed to ground with a 0.1 µF capacitor.
For most applications, the tight relationship between IREF and IFS
eliminates the need for trimming IREF. If required, full-scale
trimming can be accomplished by adjusting the value of R14, or
by using a potentiometer for R14. An improved method of fullscale trimming that eliminates potentiometer T.C. effects is
shown in the recommended full-scale adjustment circuit
(Figure 27).
Using lower values of reference current reduces negative power
supply current and increases reference amplifier negative
common-mode range. The recommended range for operation
with a dc reference current is 0.2 mA to 4.0 mA.
REFERENCE AMPLIFIER COMPENSATION FOR
MULTIPLYING APPLICATIONS
AC reference applications require the reference amplifier to be
compensated using a capacitor from Pin 16 to V−. The value of
this capacitor depends on the impedance presented to Pin 14;
for R14 values of 1.0 kΩ, 2.5 kΩ, and 5.0 kΩ, minimum values
of CC are 15 pF, 37 pF, and 75 pF. Larger values of R14 require
proportionately increased values of CC for proper phase margin,
so the ratio of CC (pF) to R14 (kΩ) = 15.
For fastest response to a pulse, low values of R14 enabling small
CC values should be used. If Pin 14 is driven by a high impedance
such as a transistor current source, none of the preceding values
suffice, and the amplifier must be heavily compensated, which
decreases overall bandwidth and slew rate. For R14 = 1 kΩ and
CC = 15 pF, the reference amplifier slews at 4 mA/µs, enabling a
transition from IREF = 0 to IREF = 2 mA in 500 ns.
Operation with pulse inputs to the reference amplifier can be
accommodated by an alternate compensation scheme. This
technique provides lowest full-scale transition times. An internal
clamp allows quick recovery of the reference amplifier from a
cutoff (IREF = 0) condition. Full-scale transition (0 mA to 2 mA)
occurs in 120 ns when the equivalent impedance at Pin 14 is
200 Ω and CC = 0. This yields a reference slew rate of 16 mA/µs,
which is relatively independent of the RIN and VIN values.
LOGIC INPUTS
The DAC08 design incorporates a unique logic input circuit
that enables direct interface to all popular logic families and
provides maximum noise immunity. This feature is made
possible by the large input swing capability, 2 µA logic input
current, and completely adjustable logic threshold voltage. For
V− = −15 V, the logic inputs may swing between −10 V and
+18 V. This enables direct interface with 15 V CMOS logic, even
when the DAC08 is powered from a 5 V supply. Minimum
input logic swing and minimum logic threshold voltage are
given by
V− + (IREF × 1 kΩ) + 2.5 V
The logic threshold may be adjusted over a wide range by placing
an appropriate voltage at the logic threshold control pin (Pin 1,
VLC). Figure 16 shows the relationship between VLC and VTH
over the temperature range, with VTH nominally 1.4 above VLC.
For TTL and DTL interface, simply ground Pin 1. When
interfacing ECL, an IREF = 1 mA is recommended. For interfacing
other logic families, see Figure 32. For general set-up of the
logic control circuit, note that Pin 1 sources 100 µA typical;
external circuitry should be designed to accommodate this
current.
Rev. C | Page 13 of 20
DAC08
Fastest settling times are obtained when Pin 1 sees a low
impedance. If Pin 1 is connected to a 1 kΩ divider, for example,
it should be bypassed to ground by a 0.01 µF capacitor.
cryptographic applications and further reduces the size of the
power supply bypass capacitors.
ANALOG OUTPUT CURRENTS
The nonlinearity and monotonicity specifications of the DAC08
are guaranteed to apply over the entire rated operating temperature range. Full-scale output current drift is low, typically
±10 ppm/°C, with zero-scale output current and drift essentially
negligible compared to 1/2 LSB.
Both true and complemented output sink currents are provided
where IO + IO = IFS. Current appears at the true (IO) output when
a 1 (logic high) is applied to each logic input. As the binary
count increases, the sink current at Pin 4 increases proportionally,
in the fashion of a positive logic DAC. When a 0 is applied to
any input bit, that current is turned off at Pin 4 and turned on at
Pin 2. A decreasing logic count increases IO as in a negative or
inverted logic DAC. Both outputs may be used simultaneously.
If one of the outputs is not required, it must be connected to
ground or to a point capable of sourcing IFS; do not leave an
unused output pin open.
Both outputs have an extremely wide voltage compliance
enabling fast direct current-to-voltage conversion through a
resistor tied to ground or other voltage source. Positive compliance is 36 V above V− and is independent of the positive supply.
Negative compliance is given by
V− + (IREF × 1 kΩ) + 2.5 V
The dual outputs enable double the usual peak-to-peak load
swing when driving loads in quasi-differential fashion. This
feature is especially useful in cable driving, CRT deflection and
in other balanced applications such as driving center-tapped
coils and transformers.
POWER SUPPLIES
The DAC08 operates over a wide range of power supply
voltages from a total supply of 9 V to 36 V. When operating at
supplies of ±5 V or lower, IREF ≤ 1 mA is recommended. Low
reference current operation decreases power consumption and
increases negative compliance (Figure 11), reference amplifier
negative common-mode range (Figure 14), negative logic input
range (Figure 15), and negative logic threshold range (Figure 16).
For example, operation at −4.5 V with IREF = 2 mA is not
recommended because negative output compliance would be
reduced to near zero. Operation from lower supplies is possible;
however, at least 8 V total must be applied to ensure turn-on of
the internal bias network.
Symmetrical supplies are not required, as the DAC08 is quite
insensitive to variations in supply voltage. Battery operation is
feasible because no ground connection is required: however, an
artificial ground may be used to ensure logic swings, etc., remain
between acceptable limits. Power consumption is calculated as
follows:
PD = ( I + ) (V + ) + ( I − ) (V − )
A useful feature of the DAC08 design is that supply current is
constant and independent of input logic states. This is useful in
TEMPERATURE PERFORMANCE
The temperature coefficient of the reference resistor R14 should
match and track that of the output resistor for minimum overall
full-scale drift. Settling times of the DAC08 decrease approximately 10% at –55°C. At +125°C, an increase of about 15% is
typical.
The reference amplifier must be compensated by using a
capacitor from Pin 16 to V−. For fixed reference operation, a
0.01 µF capacitor is recommended. For variable reference
applications, refer to the Reference Amplifier Compensation for
Multiplying Applications section.
MULTIPLYING OPERATION
The DAC08 provides excellent multiplying performance with
an extremely linear relationship between IFS and IREF over a
range of 4 µA to 4 mA. Monotonic operation is maintained over
a typical range of IREF from 100 µA to 4.0 mA.
SETTLING TIME
The DAC08 is capable of extremely fast settling times, typically
85 ns at IREF = 2.0 mA. Judicious circuit design and careful
board layout must be used to obtain full performance potential
during testing and application. The logic switch design enables
propagation delays of only 35 ns for each of the 8 bits. Settling
time to within 1/2 LSB of the LSB is therefore 35 ns, with each
progressively larger bit taking successively longer. The MSB
settles in 85 ns, thus determining the overall settling time of
85 ns. Settling to 6-bit accuracy requires about 65 ns to 70 ns.
The output capacitance of the DAC08, including the package, is
approximately 15 pF; therefore the output RC time constant
dominates settling time if RL > 500 Ω.
Settling time and propagation delay are relatively insensitive to
logic input amplitude and rise and fall times, due to the high
gain of the logic switches. Settling time also remains essentially
constant for IREF values. The principal advantage of higher IREF
values lies in the ability to attain a given output level with lower
load resistors, thus reducing the output RC time constant.
Measuring the settling time requires the ability to accurately
resolve ±4 µA; therefore a 1 kΩ load is needed to provide
adequate drive for most oscilloscopes. The settling time fixture
shown in Figure 33 uses a cascade design to permit driving a
1 kΩ load with less than 5 pF of parasitic capacitance at the
measurement node. At IREF values of less than 1.0 mA, excessive

DAC08
minor sacrifice in settling time. Fastest operation can be
obtained by using short leads, minimizing output capacitance
and load resistor values, and by adequate bypassing at the
supply, reference, and VLC terminals. Supplies do not require
large electrolytic bypass capacitors because the supply current
drain is independent of input logic states; 0.1 µF capacitors at
the supply pins provide full transient protection.
RC damping of the output is difficult to prevent while maintaining adequate sensitivity. However, the major carry from
01111111 to 10000000 provides an accurate indicator of settling
time. This code change does not require the normal 6.2 time
constants to settle to within ±0.2% of the final value, and thus
settling time is observed at lower values of IREF.
DAC08 switching transients or “glitches” are very low and can
be further reduced by small capacitive loads at the output at a
