MAX5132AEEE-MAX5133BEEE
+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.

Note 1:
Accuracy is guaranteed by following the table:
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 DVOUTover the temperature range is
divided by DT and the typical reference voltage.
Note 4:
Accuracy is better than 1.0LSB for VOUT= 10mV to VDD- 180mV. Guaranteed by PSR test on end points.

_______________Detailed Description

The MAX5132/MAX513313-bit, force/sense DACs are
easily configured with a 3-wire serial interface. They
include a 16-bit data-in/data-out shift register and have a
double-buffered digital input consisting of an input regis-
ter and a DAC register. In addition, these devices
employ precision bandgap references, as well as an out-
put amplifier with accessible feedback and output pins
that can be used for setting the gain externally (Figure 1)
or for forcing and sensing applications. These DACs
are designed with an inverted R-2R ladder network
(Figure 2) that produces a weighted voltage proportion-
al to the digital input code.
Internal Reference

Both devices use an on-board precision bandgap ref-
erence with a low temperature coefficient of only
10ppm/°C (max) to generate an output voltage of +2.5V
(MAX5132) or +1.25V (MAX5133). The REF pin can
source up to 100µA and may become unstable with
capacitive loads exceeding 100pF. REFADJ can be
used for minor adjustments to the reference voltage.
The circuits in Figures 3a and 3b achieve a nominal ref-
erence adjustment range of ±1%. Connect a 33nF
capacitor from REFADJ to AGND to establish low-noise
