Description

The MAX5104 low-power, serial, voltage-output, dual 12-bit digital-to-analog converter (DAC) consumes only 500µA from a single +5V supply. The MAX5104 features Rail-to-Rail® output swing and is available in a spacesaving 16-pin QSOP package. To maximize the dynamic range, the DAC output amplifiers are configured with an internal gain of +2V/V.

The 3-wire serial interface of MAX5104 is SPI™/QSPI™/MICROWIRE™ compatible. Each DAC has a double-buffered input organized as an input register followed by a DAC register, which allows the input and DAC registers to be updated independently or simultaneously with a 16-bit serial word. Additional features include programmable powerdown (2µA), hardware power-down lockout (PDL), a separate reference voltage input for each DAC that accepts AC and DC signals, and an active-low clear input (CL) that resets all registers and DACs to zero. These devices provide a programmable logic pin for added functionality, and a serial-data output pin for daisy chaining.
