Tool/software:

TMS320F28P65 adc max error how to calculate?

which one was constant error?

which one was random error?

i know the Gain Error is constant error ,i can calibration by firmware

but the random error can't calibration by firmware

Hello Jaures,

There is no "random" error spec here. All of the error specs quoted in the table above are static forms of error - gain, offset, INL, DNL.

I assume you mean to say dynamic error. That would be reflected in the AC characteristics (SNR, THD, ENOB).

Best regards,
Ibukun

hi sir

yes!i mean dynamic error.

but how to calculate the max dynamic error.?

like max dynamic error LSB =(SNR^2 + THD^2 + SFDR^2 + SINAD^2 + OTHERS^2)^0.5
