MAX5130/MAX5131 19-1429 Rev 0 2/99 +3V/+5V, 13-Bit, Serial Voltage-Output DACs with Internal Reference General Description Features The MAX5130/MAX5131 are low-power, 13-bit, voltage- Single-Supply Operation output digital-to-analog converters (DACs) with an inter- +5V (MAX5130) nal precision bandgap reference and output amplifier. +3V (MAX5131) 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 Range full-scale output. If necessary, the user can override the +4.0955V (MAX5130) on-chip, <10ppm/C voltage reference with an external +2.04775V (MAX5131) reference. The MAX5131, operating on +3V, delivers its +2.04775V full-scale output with an internal precision ref- Built-In 10ppm/C (max) Precision Bandgap erence of +1.25V. Both devices draw only 500A of sup- Reference ply current, which reduces to 3A in power-down mode. +2.5V (MAX5130) In addition, their power-up reset feature allows for a user- +1.25V (MAX5131) selectable initial output state of either 0V or midscale and minimizes output voltage glitches during power-up. Adjustable Output Offset The serial interface is compatible with SPI, QSPI, and SPI/QSPI/MICROWIRE-Compatible, 3-Wire Serial MICROWIRE, which makes the MAX5130/MAX5131 Interface suitable for cascading multiple devices. Each DAC has a double-buffered input organized as an input register fol- Pin-Programmable Shutdown Mode and Power- lowed by a DAC register. A 16-bit shift register loads data Up Reset (0V or Midscale Output Voltage) into the input register. The DAC register may be updated independently or simultaneously with the input register. Buffered Output Capable of Driving 5k 100pF Both devices are available in a 16-pin QSOP package or 420mA Loads and are specified for the extended-industrial (-40C to Space-Saving 16-Pin QSOP Package +85C) temperature range.
