MAX5741EUB+T Datasheet MAX5741EUB+, MAX5741AUB+T, MAX5741AUB+ | P1-P3

General Description

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

package (5mm

3mm). The wide supply voltage range of +2.7V to

+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

. 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 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
