The MAX5104 low-power, serial, voltage-output, dual
12-bit digital-to-analog converter (DAC) consumes only
500µA from a single +5V supply. This device features
Rail-to-Rail
saving 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 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 power-
down (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.
