Has anyone used the Analog Devices AD5301 DAC? I'm trying to use it to output a variable voltage based on an operator selection but can't get anything out of the DAC.
I have confirmed the correct command sequence going into the chip with a logic analyzer. In sending a 0x55 byte, I have confirmed the bytes going to the chip are 0x18, 0x25, and 0x50 (in that order). The output remains absolutely flatline. I am just monitoring the output with a scope and no other load.
I saw no mention in the datasheet for an init sequence. The chip is sending the ack bits back to the micro when the command sequence is sent. It appears the communication between the micro and the chip is valid... just no output... :(
Does anyone have any experience with this chip? Any help appreciated.
Thanks.
