3V/5V, 12-Bit, Serial Voltage-Output Dual DACs

with Internal Reference

General Description

Features

The MAX5230/MAX5231 low-power, dual 12-bit voltage-

output digital-to-analog converters (DACs) feature an

internal 3ppm/°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 ref-

erence 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 hardware-

enabled 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 double-

buffered digital input. The MAX5230/MAX5231 feature

two software-selectable shutdown output impedances:

1kΩ or 200kΩ. A power-up reset feature sets DAC out-

puts at ground or at the midscale DAC code.
