Keep the full-scale audio output of the preamplifiers to
0.5VRMS. Capacitors C1 and C2 create a one-pole,
lowpass filter to attenuate any high-frequency noise
coming from the stereo audio DAC. The frequency of
the lowpass pole is represented by this equation:
If the stereo audio DAC generates an analog, current
mode, and differential audio signal, the
Typical
Application Circuit can be used to convert the signal to
single ended. The transresistance of the circuit is rep-
resented by this equation:
VOUT = IDIFF x RF
