Low-Power, Dual, Voltage-Output, 12-Bit DAC with Serial Interface
19-f58)r Rev (Y 77/99
sMylLa2ClLAlAl
Low-Power, Dual, Voltage-Output, 12-Bit DAC
General Description
The MAX5104 low-power, serial, voltage-output, dual
12-bit digital-to-analog converter (DAC) consumes only
SOOpA from a single +5V supply This device features
Rail-to-Rail) output swing and is available in a space-
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 SPITM/OSPITM/MICROWIRETM
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 16bit serial
word, Additional features include programmable power-
down (2pA), 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,
