We have used this component (DAC38J82) in several boards before. Also we used a similar component (DAC38J84) which is a 4-ch hw/sw compatible version in some boards. The issue with the mentioned batch is very strange and we did not encounter the same issue before. In this component the SPI configuration has failed; we have configured a GPIO pin and assigned it on an LED. With this batch, sometimes it is not working. We prepared it from another batch and it worked. Schematic of this section will be provided as an attachment.
