Recommended values are C1 = 10
F, R1 = 47k, R2 = 100 Ω.
C1 forms a DC blocking capacitor to the line outputs. R1 prevents the output voltage from drifting so
protecting equipment connected to the line output. R2 forms a de-coupling resistor preventing
abnormal loads from disturbing the device. Note that poor choice of dielectric material for C1 can
have dramatic effects on the measured signal distortion at the output
HEADPHONE AMPLIFIER
The WM8731/L has a stereo headphone output available on LHPOUT and RHPOUT. The output is
designed specifically for driving 16 or 32 Ω headphones with maximum efficiency and low power
consumption. The headphone output includes a high quality volume level adjustment and mute
function.
