The MAX5230/MAX5231 low-power, dual 12-bit voltageoutput
digital-to-analog converters (DACs) feature an
internal 10ppm/°C precision bandgap voltage reference
and precision output amplifiers. The MAX5231 operates
on a single 5V supply with an internal 2.5V reference and
features a 4.095V full-scale output range. The MAX5230
operates on a single 3V supply with an internal 1.25V reference
and features a 2.0475V full-scale output range.
The MAX5231 consumes only 470μA while the MAX5230
consumes only 420μA of supply current. Both devices
feature low-power (2μA) software- and hardwareenabled
shutdown modes.
The MAX5230/MAX5231 feature a 13.5MHz SPI™-,
QSPI™-, and MICROWIRE™-compatible 3-wire serial
interface. An additional data output (DOUT) allows for
daisy-chaining and read back. Each DAC has a doublebuffered
digital input. The MAX5230/MAX5231 feature
two software-selectable shutdown output impedances:
1kΩ or 200kΩ. A power-up reset feature sets DAC outputs
at ground or at the midscale DAC code.
The MAX5230/MAX5231 are specified over the extended
temperature range (-40°C to +85°C) and are available in
16-pin QSOP packages.
Applications
Industrial Process Controls
Automatic Test Equipment
Digital Offset and Gain Adjustment
Motion Control
μP-Controlled Systems
