Description

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