General Description
The MAX5722 dual,12-bit, low-power, buffered voltage-
output, digital-to-analog converter (DAC) is packaged
in a space-saving 8-pin μMAX package (5mm
3mm).
The wide supply voltage range of +2.7V to +5.5V and
112μA supply current accommodates low-power and
low-voltage applications. DAC outputs employ on-chip
precision output amplifiers that swing Rail-to-Rail
. The
MAX5722’s reference input accepts a voltage range
from 0 to V
DD
. In power-down, the reference input is
high impedance, further reducing the system’s total
power consumption.
The 20MHz, 3-wire SPI, QSPI, MICROWIRE, and
DSP-compatible serial interface save board space and
reduce the complexity of opto- and transformer-isolated
applications. The MAX5722 on-chip power-on reset
(POR) circuit resets the DAC outputs to zero and loads
the output with a 100k
resistor to ground. This pro-
vides additional safety for applications that drive valves
or other transducers that need to be off on power-up.
The MAX5722’s software-controlled power-down
reduces supply current to less than 0.3μA and provides
software-selectable output loads (1k
, 100k
, or high
impedance) while in power-down. The MAX5722 is
specified over the -40°C to +125°C automotive temper-
ature range.
