... The MAX5306 has a digital output (DOUT) that can be used for daisy-chaining multiple devices. The MAX5307 has a hardware reset input (CLR) which clears all regis- ters and DACs to zero. The MAX5306/MAX5307 have a software shutdown feature that reduces the supply cur- rent to 1µA. The MAX5306/MAX5307 feature a load DAC (LDAC) function that updates the output of all eight DACs simultaneously ...
