Part Number: ADS8339 Dear teams, Our customer using ADS8339 in his application. The VDD and Vref are all 5V. -IN is connected to GND. A 0-5V signal is connected to +IN. When the input signal is 0-2.5V, the ADC output signal is 0x0000-0xFFFF. However, when the input signal increased to 2.5V -5V, the ADC output signal is still 0x0000-0xFFFF. The MSB always 0, it doesn't change. In the datasheet of ADS8339 . It noticed: The device outputs the MSB of data on the first SCLK falling edge after the conversion is complete and continues to output the next lower data bits on every subsequent SCLK falling edge. I don't know why the MSB always 0. If you have any idea about this question please let me know. Regards, Ricardo.
