Product Number: AD1866
Greetings,
I'm testing a setup based on the AD1866 without oversampling and digital filtering, the reconstruction filter is based on the design presented in the datasheet, but I'm using a 4562 instead of a NJM2100.
The THD+N measured using MATLAB and the PC sound card is 0.2%, is this value normal?
The input signal is fed from an Arduino Due based board and the samples are stored in an SD card in PCM WAVE format at 48kHz/16bit.
Best Regards,
Daniel Almeida
