General Description
The MAX5721 dual 10-bit, low-power, buffered voltage-
output, digital-to-analog converter (DAC) is packaged
in a space-saving 8-pin MAX package (5mm
3mm). The wide supply voltage range of +2.7V to
+5.5V and 112A supply current accommodate low-
power and low-voltage applications. DAC outputs
employ on-chip precision output amplifiers that swing
rail-to-rail. The MAX5721’s reference input accepts a
voltage range from 0 to VDD. In power-down the refer-
ence input is high impedance, further reducing the sys-
tem’s total power consumption.
The 20MHz, 3-wire SPI, QSPI, MICROWIRE and
DSP-compatible serial interface saves board space
and reduces the complexity of opto- and transformer-
isolated applications. The MAX5721 on-chip power-on
reset (POR) circuit resets the DAC outputs to zero and
loads the output with a 100k
resistor to ground. This
provides additional safety for applications that drive
valves or other transducers that need to be off on
power-up. The MAX5721’s software-controlled power-
down reduces supply current to less than 0.3A and
provides software-selectable output loads (1k
, 100k,
or high impedance) while in power-down. The
MAX5721 is specified over the -40°C to +125°C auto-
motive temperature range
