The MAX5150/MAX5151 low-power, serial, voltage-out-

put, dual 13-bit digital-to-analog converters (DACs)

consume only 500µA from a single +5V (MAX5150) or

+3V (MAX5151) 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 +2.

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, 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.
