The MAX5741 quad, 10-bit, low-power, buffered volt-
age-output, digital-to-analog converter (DAC) is pack-
aged in a space-saving 10-pin µMAX
+5.5V and 229µA supply current accommodates low-
power and low-voltage applications. DAC outputs
employ on-chip precision output amplifiers that swing
rail-to-rail. The MAX5741’s reference input accepts a
voltage range from 0 to V
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 MAX5741 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
MAX5741’s software controlled power-down reduces
supply current to less than 1µA and provides software-
selectable output loads (1kΩ, 100kΩ, or high impedance)
while in power-down. The MAX5741 is specified over the
-40°C to +125°C extended temperature range and avail-
able in a 10-pin µMAX package
