Overview
19-1587; Rev 0; 11/99 Low-Power, Dual, Voltage-Output, 12-Bit DAC with Serial Interface General Description 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® 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 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.
