Low-Power, 12-Bit Voltage-Output DAC with Serial Interface
__________________General DescriptionThe MAX5302 combines a low-power, voltage-output,
12-bit digital-to-analog converter (DAC) and a precision
output amplifier in an 8-pin µMAX package. It operates
from a single +5V supply, drawing less than 280µA of
supply current.
The output amplifier’s inverting input is available to the
user, allowing specific gain configurations, remote sens-
ing, and high output current capability. This makes the
MAX5302 ideal for a wide range of applications, includ-
ing industrial process control. Other features include a
software shutdown and power-on reset.
The serial interface is SPI™/QSPI™/MICROWIRE™ com-
patible. The DAC has a double-buffered input, organized
as an input register followed by a DAC register. A 16-bit
serial word loads data into the input register. The DAC
register can be updated independently or simultaneously
with the input register. All logic inputs are TTL/CMOS-
logic compatible and buffered with Schmitt triggers to
allow direct interfacing to optocouplers.

MAX5302
Low-Power, 12-Bit Voltage-Output DAC
with Serial Interface
Detailed DescriptionThe MAX5302 contains a voltage-output digital-to-analog
converter (DAC) that is easily addressed using a simple
3-wire serial interface. The IC includes a 16-bit shift
register, and has a double-buffered input composed of
an input register and a DAC register (see Functional
Diagram). In addition to the voltage output, the amplifier’s
negative input is available to the user.
The DAC is an inverted R-2R ladder network that converts
a digital input (12 data bits plus 1 sub-bit) into an
equivalent analog output voltage in proportion to the
applied reference voltage. Figure 1 shows a simplified
circuit diagram of the DAC.
Reference InputsThe reference input accepts positive DC and AC signals.
The voltage at the reference input sets the full-scale out-
putvoltage for the DAC. The reference input voltage
range is 0 to (VDD- 1.4V). The output voltage (VOUT) is
represented by a digitally programmable voltage
source, as expressed in the following equation:
VOUT= (VREF
·NB / 4096) Gain
where NB is the numeric value of the DAC’s binary
input code (0 to 4095), VREFis the reference voltage,
and Gain is the externally set voltage gain.
The impedance at the reference input is code dependent,
ranging from a low value of 14kΩwhen the DAC has an
input code of 1554 hex, to a high value exceeding several
gigaohms (leakage currents) with an input code of
0000 hex. Because the input impedance at the reference
pin is code dependent, load regulation of the reference
source is important.
In shutdown mode, the MAX5302’s REF input enters a
high-impedance state with a typical input leakage current
of 0.001µA.
The reference input capacitance is also code dependent
and typically ranges from 15pF (with an input code of
all 0s) to 50pF (at full scale).
The MAX873 +2.5V reference is recommended for the
MAX5302.
Output AmplifierThe MAX5302’s DAC output is internally buffered by a
precision amplifier with a typical slew rate of 0.6V/µs.
Access to the output amplifier’s inverting input provides
the user greater flexibility in output gain setting/signal
conditioning (see the Applications Informationsection).
With a full-scale transition at the MAX5302 output, the
typical settling time to ±1/2LSB is 14µs when loaded
with 5kΩin parallel with 100pF (loads less than 2kΩ
degrade performance).
The amplifier’s output dynamic responses and settling
performances are shown in the Typical Operating Char-
acteristics.
Shutdown ModeThe MAX5302 features a software-programmable shut-
down that reduces supply current to a typical value of
4µA. Writing 111X XXXX XXXX XXXX as the input control
word puts the device in shutdown mode (Table 1).
In shutdown mode, the amplifier’s output and the refer-
ence input enter a high-impedance state. The serial
interface remains active. Data in the input registers is
retained in shutdown, allowing the MAX5302 to recall
the output state prior to entering shutdown. Exit shutdown
mode by either recalling the previous configuration or
