MAX5174/MAX5176
Low-Power, Serial, 12-Bit DACs with Voltage Output
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.
The 3-wire, digital, 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 i...
