Output Power:

Quiescent Current:

Check the quiescent current. Place an 8 Ω load, no input signal. V

1. Set V

2. Set an 8 Ω load (resistance) on the output connector (J5).

3. With the function generator, set a single ended signal at 1 kHz and 0.5 Vrms input signal on the negative input. Apply this

4. Place 2 oscilloscope probes on the output (differential measurement). You should get a 1Vrms output signal with a “perfect

signal either on J2 or J3 connector. As R1=R2=20k, VO1 will see 0.5 Vrms. As VO1 signal is inverted by the second

amplifier, VO2 will also see 0.5 Vrms with 180° delay. Thus, the load between VO1 and VO2 will see 1 Vrms.

sine wave.” That is to say no clipping at the minima and maxima of the sine wave.

= 5 V to power supply connector (J1).

Test Procedure for the NCP2990EVB

set to 5 V and J6 closed. You should measure around 1.7 mA.
