General Description
The MAX5170/MAX5172 low-power, serial, voltage-output, 14-bit digital-to-analog converters (DACs) feature a precision output amplifier in a space-saving 16-pin QSOP package. The MAX5170 operates from a +5V single supply and the MAX5172 operates from a +3V single supply. Both devices draw only 280µA of supply current, which reduces to 1µA in shutdown. In addition, the programmable power-up reset feature allows for a user-selectable power-up output voltage of either 0 or midscale.
