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.

The MAX5232/MAX5233 low-power, dual 10-bit voltageoutput 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 hardware- 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 doublebuffered digital input. The MAX5232/MAX5233 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 MAX5232/MAX5233 are specified over the extended temperature range (-40°C to +85°C) and are available in 16-pin QSOP packages.
