Low-Power, Dual, 12-Bit Voltage-Output DACs with Serial Interface
_______________General DescriptionThe MAX5154/MAX5155 low-power, serial, voltage-out-
put, dual 12-bit digital-to-analog converters (DACs)
consume only 500µA from a single +5V (MAX5154) or
+3V (MAX5155) supply. These devices feature Rail-to-
Rail®output swing and are 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 SPI™/QSPI™ and
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 reg-
isters to be updated independently or simultaneously
with a 16-bit serial word. Additional features include
programmable shutdown (2µA), hardware-shutdown
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 out-
put pin for daisy chaining.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
