MAX5232EEE+

P1-P3P4-P6P7-P9P10-P12P13-P15P16-P18
General Description
The MAX5232/MAX5233 low-power, dual 10-bit voltage-
output digital-to-analog converters (DACs) feature an
internal 10ppm/°C precision bandgap voltage reference
and precision output amplifiers. The MAX5233 operates
on a single 5V supply with an internal 2.465V reference
and features a 4.092V full-scale output range. The
MAX5232 operates on a single 3V supply with an internal
1.234V reference and features a 2.046V full-scale output
range. The MAX5233 consumes only 470µA while the
MAX5232 consumes only 420µA of supply current. Both
devices feature low-power (2µA) software- and hard-
ware-enabled shutdown modes.
The MAX5232/MAX5233 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 MAX5232/MAX5233 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.
The MAX5232/MAX5233 are specified over the extended
temperature range (-40°C to +85°C) and are available in
16-pin QSOP packages.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
