Octal, 14-Bit Voltage-Output DAC
with Parallel Interface for ATE
______________________________________________________________________________________

Table 4. Analog Voltage vs. Digital Code
The output amplifier multiplies V
DAC
by 2, yielding an
output voltage range of 2
REF- to 2
REF+ (Figure 1).
Further manipulation of the output voltage span is
accomplished by offsetting DUTGND. The output volt-
age of the MAX5264 is described by the following
equation:
where DATA is the numeric value of the DAC’s binary
input code, and DATA ranges from 0 to 16383
(2
14
- 1). The resolution of the MAX5264, defined as
1LSB, is described by the following equation:
(
Reference Selection
Because the MAX5264 has precision buffers on its ref-
erence inputs, the requirements for interfacing to these
inputs are minimal. Select a low-drift, low-noise refer-
ence within the recommended REF+ and REF- voltage
ranges. The MAX5264 does not require bypass capaci-
tors on its reference inputs. Add capacitors only if the
reference voltage source requires them to meet system
specifications.
Minimizing Output Glitch
The MAX5264’s internal deglitch circuitry is enabled on
the falling edge of
LD
. Therefore, to achieve optimum
performance, drive
LD
low after the inputs are either
latched or steady state. This is best accomplished by
having the falling edge of
LD
occur at least 50ns after
the rising edge of
CS
.
Power Supplies, Grounding,
and Bypassing
For optimum performance, use a multilayer PC board
with an unbroken analog ground. For normal operation,
connect the four DUTGND pins directly to the ground
plane. Avoid sharing the connections of these sensitive
pins with other ground traces.
As with any sensitive data-acquisition system, connect
the digital and analog ground planes together at a sin-
gle point, preferably directly underneath the MAX5264.
Avoid routing digital signals underneath the MAX5264
to minimize their coupling into the IC.
For normal operation, bypass V
DD
and V
SS
with 0.1μF
ceramic chip capacitors to the analog ground plane. To
enhance transient response and capacitive drive capa-
bility, add 10μF tantalum capacitors in parallel with the
ceramic capacitors. Note, however, that the MAX5264
does not require the additional capacitance for stability.
Bypass V
CC
with a 0.1μF ceramic chip capacitor to the
digital ground plane.
Power-Supply Sequencing
To guarantee proper operation of the MAX5264, ensure
that power is applied to V
DD
before V
SS
and V
CC
. Also
ensure that V
SS
is never more than 300mV above
ground. To prevent this situation, connect a Schottky
diode between V
SS
and the analog ground plane, as
shown in Figure 3. Do not power up the logic input pins
before establishing the supply voltages. If this is not
possible and the digital lines can drive more than
10mA, place current-limiting resistors (e.g., 470
) in
series with the logic pins.
