+5V/+3V, 13-Bit, Serial, Force/Sense DACs with 10ppm/°C Internal Reference
General Description
The MAX5132/MAX5133 low-power, 13-bit, voltage-output digital-to-analog converters (DACs) feature an internal precision bandgap reference and output amplifier. The MAX5132 operates on a single +5V supply with an internal reference of +2.5V and offers a configurable output amplifier. If necessary, the user can override the onchip, <10ppm/°C voltage reference with an external reference. The MAX5133 has the same features as the MAX5132 but operates from a single +3V supply and has an internal +1.25V precision reference. The useraccessible inverting input and output of the amplifier allows specific gain configurations, remote sensing, and h i g h output drive capability for a wide range of force/sense applications. 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 reduces output glitches during power-up. The serial interface is compatible with SPITM, QSPITM, a n d MICROWIRETM, which makes the MAX5132/ MAX5133 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) operating temperature range. For pin-compatible 14-bit upgrades, see the MAX5171/MAX5173 data s h e e t ; for pin-compatible 12-bit versions, see the MAX5122/MAX5123 data sheet. o Single-Supply Operation +5V (MAX5132) +3V (MAX5133) o Built-In 10ppm/°C max Precision Bandgap Reference +2.5V (MAX5132) +1.25V (MAX5133) 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 for the 12-Bit MAX5122/MAX5123 o Pin-Compatible 14-Bit Upgrades Available (MAX5171/MAX5173)

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.
