... The MAX5308 has a digital output (DOUT) that can be used for daisy-chaining multiple devices. The MAX5309 has a hardware reset input (CLR) which clears all regis- ters and DACs to zero. The MAX5308/MAX5309 have a software shutdown feature that reduces the supply cur- rent to 1µA. The MAX5308/MAX5309 feature a load DAC (LDAC) function that updates the output of all eight DACs simultaneously ...
