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.
♦ Single-Supply Operation
+5V (MAX5132)
+3V (MAX5133)
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
hig h outp ut d rive c a p a b ility for a wid e ra ng e 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.
♦ Built-In 10ppm/°C max Precision Bandgap Reference
+2.5V (MAX5132)
+1.25V (MAX5133)
♦ SPI/QSPI/MICROWIRE-Compatible, 3-Wire Serial
Interface
♦ Pin-Programmable Shutdown-Mode and Power-
Up Reset (0V or Midscale Output Voltage)
♦ Buffered Output Capable of Driving 5kΩ 100pF
or 4–20mA Loads
♦ Space-Saving 16-Pin QSOP Package
♦ Pin-Compatible Upgrades for the 12-Bit
MAX5122/MAX5123
The serial interface is compatible with SPI™, QSPI™,
a nd MICROWIRE™, whic h ma ke s 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.
