MAX5230AEEE
3V/5V, 12-Bit, Serial Voltage-Output Dual DACs with Internal Reference
General DescriptionThe MAX5230/MAX5231 low-power, dual 12-bit voltage-
output digital-to-analog converters (DACs) feature an
internal 3ppm/°C precision bandgap voltage reference
and precision output amplifiers. The MAX5231 operates
on a single 5V supply with an internal 2.5V reference and
features a 4.095V full-scale output range. The MAX5230
operates on a single 3V supply with an internal 1.25V ref-
erence and features a 2.0475V full-scale output range.
The MAX5231 consumes only 470µA while the MAX5230
consumes only 420µA of supply current. Both devices
feature low-power (2µA) software- and hardware-
enabled shutdown modes.
The MAX5230/MAX5231 feature a 13.5MHz SPI™-,
QSPI™-, and MICROWIRE™-compatible 3-wire serial
interface. An additional data output (DOUT) allows for
daisy-chaining and read back. Each DAC has a double-
buffered digital input. The MAX5230/MAX5231 feature
two software-selectable shutdown output impedances:
1kΩor 200kΩ. A power-up reset feature sets DAC out-
puts at ground or at the midscale DAC code.
The MAX5230/MAX5231 are specified over the extended
temperature range (-40°C to +85°C) and are available in
16-pin QSOP packages.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Note 1:Accuracy is guaranteed as shown in the following table:
Note 2:Offset is measured at the code closest to 10mV.
Note 3:Temperature coefficient is determined by the box method in which the maximum ∆VOUTover the temperature range is
divided by ∆T.
Note 4:DC crosstalk is measured as follows: set DAC A to midscale, and DAC B to zero, and measure DAC A output; then change
DAC B to full scale, and measure ∆VOUTfor DAC A. Repeat the same measurement with DAC A and DAC B interchanged.
DC crosstalk is the maximum ∆VOUTmeasured.
Note 5:Accuracy is better than 1LSB for VOUT_= 10mV to VDD- 180mV.
Note 6:Guaranteed by design, not production tested.
Note 7:RLOAD= ∞and digital inputs are at either VDDor DGND.
