AD7357 is 14 bit , Due to DC accuracy concern , I need >0.3%
DC accuracy = LSB[all of LSB , see the attachment as below ] / (2^14) , = 133 LBS / 16384 * 100% = 0.8%
AM I right ? or any part could meet this request ? ( Should meet automotive standard )
I have attached some list of ADC that were Automotive Qualified. Do you have specific paramater that you are looking for an ADC? like Throughput rate, no. of channels, or Resolution.
You can also visit the Analog Devices website and filter some of the paramater you want to search. Please refer to this link http://www.analog.com/ps/psthandler.aspx?pstid=10169&la=en .
