Hi team,
My customer is evaluating ADS127L11EVM and got unexpected aliasing frequency with hundreds Hz error.
What kind of cause can you think of for this phenomenon?
ex.)
OSR:32
Vin: 2.5 Vp-p
Input Frequency: 300kHz
expected aliasing frequency: 75kHz
->Displayed in FFT with Analog calculator: 75.348 kHz
Best regards,
Yuto
