+5V/+3V, 13-Bit, Serial, Force/Sense DACs
with 10ppm/°C Internal Reference
General Description
The MAX5132/MAX5133 low-power, 13-bit, voltage-out-
put digital-to-analog converters (DACs) feature an inter-
nal precision bandgap reference and output amplifier.
The MAX5132 operates on a single +5V supply with an
internal reference of +2.5V and offers a configurable out-
put amplifier. If necessary, the user can override the on-
chip, <10ppm/°C voltage reference with an external
reference. The MAX5133 has the same features as the
MAX5132 but operates from a single +3V supply and
has an internal +1.25V precision reference. The user-
accessible inverting input and output of the amplifier
allows specific gain configurations, remote sensing, and
high output drive capability for a wide range of
force/sense applications. Both devices draw only 500µA
of supply 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 mid-
scale and reduces output glitches during power-up.
The serial interface is compatible with SPI™, QSPI™,
and MICROWIRE™, which makes the MAX5132/
MAX5133 suitable for cascading multiple devices. Each
DAC has a double-buffered input organized as an input
register followed 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) operating temperature range. For pin-compati-
ble 14-bit upgrades, see the MAX5171/MAX5173 data
sheet; for pin-compatible 12-bit versions, see the
MAX5122/MAX5123 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:
32
65
To Code:
8191
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
and the typical reference voltage.
Note 4:
Accuracy is better than 1.0LSB for V
OUT
= 10mV to V
DD
- 180mV. Guaranteed by PSR test on end points.
Note 5:
R
LOAD
