The 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
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.
