Hello, in one of our recent designs we use this Quad-DAC and found a defect to channel B for multiple PCBs. Currently, we've seen 4 devices failing after several months of operation. All devices show a defect to channel B which is stuck at approx 800mV, while all other channels remain functional. Is this a known issue and how can we prevent it? We evaluated the input signals upon power-up and found that we already raise the CLR# input pin to 3V3 while the supply voltage (5V) is not yet present or was ramping up simultaneously. Can this cause this kind of failure? As we are preparing the design for mass production we need to know if this failure can be prevented by delaying the input signals until the supply voltage is present, or if we need to take additional measures on the PCB. Channel B is connected to another device (at the same voltage level) via a 40kOhm resistor, so large currents in the output are not expected. After replacing the devices all channels are working fine. Thanks..
