NCP2809A: R1, R2, R3 and R4
NCP2809B: R1, R2, R3 and R4 must be connected. J1 and J4 must be left
Test Procedure:
1. Connect J7 to Gnd (Device Off).
2. Set Vp = 5 V to power supply connector.
3. Set two 16 Ω load (resistance) on the 3 points output connector (J3).
4. With your Function Generator set a sine wave signal at 1 kHz and 500 mVrms input signal. Connect it
to the input connector (J2): between IN_R and GND for the right output and once measured, between
IN_L and GND for the left one.
Two 16 Ω loads
Oscilloscope
must not be soldered. J1, J4 must be closed.
