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...

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!
Active low-pass filter using STM32G4 Series OPAMP and an external capacitor STM32G4 Series OPAMP VINP VDDA + VINN - Cext VOUT R2 R1 feedback resistor Here is an application example where : • The sampling rate of the ADC is 100 kHz • The sampling bandwidth is 10kHz ...
This paper presents a high linearity wideband sharp roll-off Opamp-RC low-pass filter (LPF) for Ultra wideband (UWB) applications. The proposed LPF is composed of three biquads' transfer functions with different Q-factors in series. Sharp roll-off is attributed to the steep slope of the pea...

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...
