MAX5130：+3V/+5V、13位、串行、电压输出DAC，内置电压基准

业内首款10ppm/°C、内置基准、13位DAC

The MAX5130/MAX5131 are low-power, 13-bit, voltage-output digital-to-analog converters (DACs) with an internal precision bandgap reference and output amplifier. The MAX5130 operates on a single +5V supply with an internal reference of +2.5V, and is capable of a +4.0955V full-scale output. If necessary, the user can override the on-chip, <10ppm/°C voltage reference with an external reference. The MAX5131, operating on +3V, delivers its +2.04775V full-scale output with an internal precision reference of +1.25V. Both devices draw only 500µA of supply current, which reduces to 3µA in power-down mode. In addition, their power-up reset feature allows for a user-selectable initial output state of either 0V or midscale and minimizes output voltage glitches during power-up. The serial interface is compatible with SPI™, QSPI™, and MICROWIRE™, which makes the MAX5130/MAX5131 suitable for cascading multiple devices. Each DAC has a double-buffered input organized as an input register followed by a DAC register. A 16-bit shift register loads data into the input register. The DAC register may be updated independently or simultaneously with the input register. Both devices are available in a 16-pin QSOP package and are specified for the extended-industrial (-40°C to +85°C) temperature range. For pin-compatible 14-bit upgrades, see the MAX5170/MAX5172 data sheet; for pin-compatible 12-bit versions, see the MAX5120/ MAX5121 data sheet.
