Equipment Needed:

The procedure described below can be used for each schematic.

This is the only test performed. You could also check the quiescent current. Place two 16

Ohm loads, no input signal, Vp set to 5V and you should measure around 1.9 mA.

• DC Power Supply

• Function Generator

• Oscilloscope

• Digital Multimeter

• Set Vp = 5 V to power supply connector.

• Set two 16 Ohm loads (resistance) on the 3 points of output connector J3 and J9.

• With your Function Generator, set a sinewave signal at 1kHz and 1Vrms for the

• In case of the big output capacitors schematic, place 1 oscilloscope probe on

• In case of the capless schematic, place 2 oscilloscope probes on each output

• During the test with the capless schematic, be careful not to connect the

GND for the right output and once measured, between IN_L and GND for the

left one.

each output (Right & Left) and you should get a 1Vrms output signal with a

"perfect sinewave". That is to say no clipping at the minimum and maximum

of the sinewave.

solder another NCP2809A.
