Part Number: TIC12400
I've attached my schematic. HS_LS_IO.pdf I am converting a value on IN10 and it has an offset error. For example:
10V = 10.577
5V = 5.677 etc
From my schematic, if you follow IN1 (upper middle of the page), it goes through a 10K/(35.7K + 10K) divider and then in to IN10. So, when I convert it for 10V, the 32 bit register coming back is 90 00 03 16 and that is in hex, left to right is MSB to LSB. The raw adc value is in bits 1 to 11 which is 18B or decimal value 395. Since the adc is a 6V full scale part and 10 bit, that means each bit is 6V/1024 = 5.859mV/lsb. The voltage divider is 0.2188. So, the voltage value is (395 x 0.005859)/0.2188 = 10.577V. Can you provide some guidance on how to handle this error?
