5. Connect J7 to Vp (Device On).
6. Place 2 oscilloscope probes on each output (Right & Left) and the virtual ground and you should get a
500 mVrms differential output signal with a "perfect sine wave" in case of A version. That is to say no
clipping at the minimum and maximum of the sine wave. When using B version with R2=R4=20 kΩ and
R1=R3=40 kΩ, you should get a 1 Vrms differential output signal.
7. During the test with the capless schematic, be careful not to connect the ground to the virtual ground
on the output!
8. (Optional) To check the quiescent current, place two 16 Ω load, no input signal, Vp set to 5V. The
current should measure around 1.9 mA.
