Re: Offset of MCP3201 ADC

Any A/D has the offset that is the nature of the A/D and the offset is independent of the amplitude of the input signal, we have many customers using MCP3201 in their applications and never get this kind of problem, please check the other portion of the circuit in your application, for example, maybe you have OP Amp as an amplifier or buffer in front of A/D, sometimes the offset is caused by OP Amp, Microchip have many good OP Amp which you can choose for your applications.

Offset of MCP3201 ADC

I am using a MCP3201 A/D IC for my analog input convertion. I am using a 5V supply and a 2.55V refrerence.

I found a problem with my convertion result. The result of the A/D convertion have an offset,
and the offset become bigger according to the input voltage when it become bigger.

Ex. for a 1V input the result will go approx. 1.01 V and the result will reach 2.55V if the input is about 2.50V.
Can you please tell me how to solve the offset problem?
