I am facing some problem in Reading Analogue values from AD7490. I always received FF from ADC. If any one interface this ADC with 8 bit Microcontroller then please share your experience.
I am using Microcontroller with 11.0592 MHz and connected with SPI pins I was confused due to arrangement of 12bit command word.
According to the datasheet 12bit command word with 12th bit MSB (write) and LSB is Coding bit. However We have 16 bit integer so I m confused that either I need to send 0x8330 command byte or 0x08333 command byte.
