MAX5170/MAX5172
Low-Power, Serial, 14-Bit DACs with Voltage Output
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.
The 3-wire serial interface is compatible with SPI™, QSPI™, and MICROWIRE™ standards. An input register followed by a DAC register provides a doublebuffered input, allowing the input and DAC registers to be updated independently or simultaneously with a 16bit serial word. Additional features include software and hardware shutdown, shutdown lockout, a hardware clear pin, and a reference input ca...
