Settling Time
Settling time is the time required from a code
transition until the DAC output reaches within g
LSB of
the final output value Full-scale settling time requires a zero
to full-scale or full-scale to zero output change
Full-Scale Error
Full scale error is a measure of the output
error between an ideal DAC and the actual device output
Ideally for the DAC1006 series full-scale is VREFb1 LSB
For VREFeb10V and unipolar operation VFULL-SCA-
LE
e
100000V b98mVe99902V Full-scale error is adjust-
able to zero
Monotonicity
If the output of a DAC increases for increas-
ing digital input code then the DAC is monotonic A 10-bit
DAC with 10-bit monotonicity will produce an increasing an-
alog output when all 10 digital inputs are exercised A 10-bit
DAC with 9-bit monotonicity will be monotonic when only
the most significant 9 bits are exercised Similarly 8-bit
monotonicity is guaranteed when only the most significant 8
bits are exercised
20 DOUBLE BUFFERING
These DACs are double-buffered microprocessor compati-
ble versions of the DAC1020 10-bit multiplying DAC The
addition of the buffers for the digital input data not only al-
lows for storage of this data but also provides a way to
assemble the 10-bit input data word from two write cycles
when using an 8-bit data bus Thus the next data update for
the DAC output can be made with the complete new set of
10-bit data Further the double buffering allows many DACs
in a system to store current data and also the next data The
updating of the new data for each DAC is also not time
critical When all DACs are updated a common strobe sig-
nal can then be used to cause all DACs to switch to their
new analog output levels
30 TTL COMPATIBLE LOGIC INPUTS
To guarantee TTL voltage compatibility of the logic inputs a
novel bipolar (NPN) regulator circuit is used This makes the
input logic thresholds equal to the forward drop of two di-
odes (and also matches the temperature variation) as oc-
curs naturally in TTL The basic circuit is shown in
Figure 1
A curve of digital input threshold as a function of power
supply voltage is shown in the Typical Performance Charac-
teristics section
40 APPLICATION HINTS
The DC stability of the VREF source is the most important
factor to maintain accuracy of the DAC over time and tem-
perature changes A good single point ground for the analog
signals is next in importance
These MICRO-DAC converters are CMOS products and
reasonable care should be exercised in handling them prior
to final mounting on a PC board The digital inputs are pro-
tected but permanent damage may occur if the part is sub-
jected to high electrostatic fields Store unused parts in con-
ductive foam or anti-static rails
41 Power Supply Sequencing
Decoupling
Some IC amplifiers draw excessive current from the Analog
inputs to Vb when the supplies are first turned on To pre-
vent damage to the DAC
an external Schottky diode con-
nected from IOUT1 or IOUT2 to ground may be required to
prevent destructive currents in IOUT1 or IOUT2 If an LM741
or LF356 is used
these diodes are not required
The standard power supply decoupling capacitors which are
used for the op amp are adequate for the DAC
