The MAX5130/MAX5131 are low-power, 13-bit, voltageoutput
digital-to-analog converters (DACs) with an internal
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 reference
of +1.25V. 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 userselectable
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 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) 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.
Applications
Industrial Process Control
Automatic Test Equipment (ATE)
Digital Offset and Gain Adjustment
Motion Control
μP-Controlled Systems
