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.
Dave
