... MAX5741’s software controlled power-down reduces supply current to less than 0.1µA 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 ...

... The output DD allow the internal bias to wake-up. Power-down mode reduces current consumption to 0.3µA. 10 The MAX5741 digital interface is a standard 3-wire con- nection compatible with SPI/QSPI/MICROWIRE/DSP interfaces. The chip-select input (CS) frames the serial is the voltage at REF data loading at DIN. Immediately following CS high-to- ...

... The DAC output is not updated until data is written to the DAC register. See Table 2 for a list of serial-inter- face programming commands. The MAX5741 has an internal POR circuit. At power-up all DACs are powered-down and OUT_ is terminated to GND through 100kΩ resistors. Contents of input and DAC registers are cleared to all zero. 8µ ...
