13.3 Test conditions
The capacitor Cb is recommended for stability improvement. The value may vary between
10 nF and 100 nF. This capacitor should be placed close to the IC between pin 12 and
pin 13.
The standard application is stereo headphone single-ended with a 32

low input mode, band-pass filter: 22 Hz to 30 kHz. The total harmonic distortion as a
function of frequency was measured with low-pass filter of 80 kHz. The quiescent current
has been measured without any load impedance.
In applications with coupling capacitors towards the load, an electrolytic capacitor has to
be connected to pin 4 (SVRR).
