a two-op-amp rectifier, and then an op-amp lowpass filter. That’s five op-amps for each band (there are 14 bands) plus the support circuitry. And that’s just the input section!
Fiio X1 使用的OPA2322+ISL28291放大器, Xduoo X3 使用了两个OPA1612(low pass filter、voltage amp)+LMH6643(current amp) Fiio X3II 使用的 OPA1642 + LMH6643 比较有意思的是备受推崇的 Fiio E12(纯粹的 amp)用的是 OPA1611 + LME49600,看起来 OPA1642 还是要弱一点呀。 功放芯片也有类似的 THD、SNR...
Since the main interest in this book is in the design and implementation of continuous-time low-pass filters for integrated radio receivers, rather than concentrating on stand-alone filter circuits, both multicarrier receiver implementations are also briefly presented in this chapter. Moreover, since...

For example, it is very problematic to put a capacitor in its feedback in order to obtain a low-pass filter. But now we have OPA1656, OPA1612, OPA1632, and other excellent OPs for I/V. Not so many opamps designed "for audio" are truly good. In most cases, industrial operational ...
Jonathan Nguyen5 年多前 TI__Expert4555points Hari, The RC circuit is just a low pass filter that essentially averages out the voltage seen on the data input. For lowpass filters: Vout = Vin*(Xc/Z) Where Xc = 1/(2*pi*f*C) ...
