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.
♦ Single-Supply Operation

+3V (MAX5131)
♦ Full-Scale Output Range

♦ Built-In 10ppm/°C (max) Precision Bandgap
Reference
+2.5V (MAX5130)
+1.25V (MAX5131)
♦ Adjustable Output Offset
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.
♦ 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
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
