General Description

The MAX5174/MAX5176 low-power, serial, voltage-output, 12-bit digital-to-analog converters (DACs) feature a precision output amplifier in a space-saving 16-pin QSOP package. The MAX5174 operates from a single +5V supply, and the MAX5176 operates from a single +3V 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 output voltage state of either 0 or midscale.
