TMS320F2800137: What is the actual sampling accuracy of the built-in ADC

Part Number: TMS320F2800137

What is the actual sampling accuracy of this product? We have seen 12 bits in the specification sheet and would like to ask what is the actual achievable sampling accuracy and how many bits can be achieved?

    Hello Tony,

    The ADC is a 12-bit SAR ADC. The data sheet provides details on static and dynamic error limits for this device. If you are referring to dynamic performance, there is an ENOB (Effective Number of Bits, factoring in SNR) specification in the data sheet. We also have graphs that show ENOB on a per-pin basis.

    Best regards,
