+3V/+5V, 13-Bit, Serial Voltage-Output DACs with Internal Reference
General Description
The MAX5130/MAX5131 are low-power, 13-bit, voltageoutput 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 userselectable initial output state of either 0V or midscale and minimizes output voltage glitches during power-up. The serial interface is compatible with SPITM, QSPITM, and MICROWIRETM, 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 u p g r a d e s , see the MAX5170/MAX5172 data sheet; for pin-compatible 12-bit versions, see the MAX5120/ MAX5121 data sheet. o Single-Supply Operation +5V (MAX5130) +3V (MAX5131) o Full-Scale Output Range +4.0955V (MAX5130) +2.04775V (MAX5131) o Built-In 10ppm/°C (max) Precision Bandgap Reference +2.5V (MAX5130) +1.25V (MAX5131) o Adjustable Output Offset o SPI/QSPI/MICROWIRE-Compatible, 3-Wire Serial Interface o Pin-Programmable Shutdown Mode and PowerUp Reset (0V or Midscale Output Voltage) o Buffered Output Capable of Driving 5k || 100pF or 420mA Loads o Space-Saving 16-Pin QSOP Package o Pin-Compatible Upgrades to the 12-Bit MAX5120/MAX5121 o Pin-Compatible 14-Bit Upgrades Available (MAX5170/MAX5172)

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.
