We are using AD7821 ADC (8 bit) in one biomedical instrument. But, now to improve accuracy, we need 12 Bit ADC. Since we have current stock of PCB's where AD7821 is used, is there any ADC IC which is pin to pin compatible to AD7821 with 12 Bit resolution…
Hi Postino,
Here are some list of ADC that could be suitable for your application. You may also wanted to check the ADI website and do a parametric search and put in parameters on the ADC that you wanted to search. Please refer to the link below.
