Product Number: EVAL-AD2S1205SDZ
I'm trying to use the EVAL-AD2S1205SDZ evaluation board to acquire the position data from a synchro/resolver through the SPI communication. For angles between 180° and 360° I get to read the right data (2048 - 4095), However for all the angles between 0° and 180° the SPI frame is tied to GND so the 16 bits are zeros. I verified many times the datasheet and the SPI signals provided by our microcontroller are OK. We also tested on the parallel mode and it works fine but unfortunately, we are forced to use the SPI interface. Should we replace the integrated circuit from the evaluation board or there is any other solution?
