Part Number: ADS1217 Everything seems to be working ok, but I dont know why the DRDYn pin is always driving this signal even after power up!!! Below pin status: ( I am not issuing any commands to ADC ) CSn = high SCLK = low CLK = 8MHZ DIN = low DSYNC = high DOUT = low POL = low RESETn = High DRDY = "clocking" (high = 20us, low = 30ms) Register settings: REG0 = 0x0C = fosc/128 + Int Vref enable + Int Vref = 2.5V + Buffer disable + MSb transmitted first REG 9 = 0x47 = Unipolar + Auto setting mode + Decimation default D10 to D8 = 7 Any suggestions? Thank you Fausto Bartra
