What is a good substitute for IC AD7663?
I moved your question to the Precision ADC Q&A page for support. To help make an suitable suggestion, could you share some details about your ADC requirements such as:
1. What is the typical input voltage range in volts? Do you require the integrated input voltage range scalar?
2. Are you looking for the same throughput and resolution as the AD7663?
3. Do you have any other design considerations or feature requirements such as power constraints, digital interface preference, etc.?
