Evo još jednog dodatka koji može biti interesantan. Odgovor je direktno od Toppinga. Samo sam ja u zabuni pisao PCM 1656 ane OPA1656. Jbg!
However, in E30 II, we have fine-tuned the LPF circuit behind the DAC to maximize the performance of the DAC, and we believe that replacing the op-amps on the user's own will result in poorer performance or unstable operation of the circuit, so it is highly recommended not to do so. The PCM1656 you mentioned should be the OPA1656 model, which is pin-compatible with the op-amps we use on our boards, but we don't make any guarantee in other aspects.
