10-Bit, Low-Power, Dual, Voltage-Output
DAC with Serial Interface
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 µMAX
®
package (5mm
3mm). The wide supply voltage range of +2.7V to
+5.5V and 112µA 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 V
DD
. 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 100kΩ 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 0.3µA and
provides software-selectable output loads (1kΩ, 100kΩ,
or high impedance) while in power-down. The
MAX5721 is specified over the -40°C to +125°C auto-
motive temperature range
