+3V/+5V, 13-Bit, Serial Voltage-Output DACs
with Internal Reference
General Description
The MAX5130/MAX5131 are low-power, 13-bit, voltage-
output digital-to-analog converters (DACs) with an inter-
nal precision bandgap reference and output amplifier.
The MAX5130 operates on a single +5V supply with an
internal reference of +2.5V, and is capable of a +4.0955V
full-scale output. If necessary, the user can override the
on-chip, <10ppm/°C voltage reference with an external
reference. The MAX5131, operating on +3V, delivers its
+2.04775V full-scale output with an internal precision ref-
erence of +1.25V. Both devices draw only 500µA of sup-
ply current, which reduces to 3µA in power-down mode.
In addition, their power-up reset feature allows for a user-
selectable initial output state of either 0V or midscale and
minimizes output voltage glitches during power-up.
The serial interface is compatible with SPI™, QSPI™, and
MICROWIRE™, which makes the MAX5130/MAX5131
suitable for cascading multiple devices. Each DAC has a
double-buffered input organized as an input register fol-
lowed by a DAC register. A 16-bit shift register loads data
into the input register. The DAC register may be updated
independently or simultaneously with the input register.
Both devices are available in a 16-pin QSOP package
and are specified for the extended-industrial (-40°C to
+85°C) temperature range. For pin-compatible 14-bit
upgrades, see the MAX5170/MAX5172 data sheet;
for pin-compatible 12-bit versions, see the MAX5120/
MAX5121 data sheet.

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.

Accuracy Guaranteed
From Code:

To Code:
8191

Note 2:
Offset is measured at the code closest to 10mV.
Note 3:
The temperature coefficient is determined by the “box” method in which the maximum
∆V
OUT
over the temperature range is
divided by
∆T.
Note 4:
Accuracy is better than 1.0LSB for V
OUT
= 10mV to (V
