Equipment Needed:

Sine Wave Generator with Differential Output

Oscilloscope

Power Supply

Digital Voltmeter

Digital Amp Meter

Signal Source Setup:

The NCP4894 requires a differential signal to drive the audio amplifier. This is done

using a waveform generator with a differential output signal. Set a sinewave differential

signal on the input connector (J2). The middle point is connected to ground while INM

and INP signals are in opposite phases. For each signal, Vin = 1 Vrms and f = 1 kHz.

NCP4894 Test:

1) Jumpers J5 & J4 should be open.

2) Set the Power Supply to 5 V with a current limit of at least 800 mA.

3) Connect Ground and Vp = 5 V to power supply connector (J1). There should be no

4) Connect an 8 Ω load (resistance) across the output connector (J3). Close J4 connector.

5) Connect oscilloscope probes on each output (OUTA & OUTB) and configure the

6) Connect the differential signal from the waveform generator to the differential input

7) Measure (OUTA-OUTB), you should see a 2 Vrms output signal with a "perfect 1

current flowing from the Vp. The measurement should be at maximum 600 nA.

The dc current measurement on Vp line should be around 2.2 mA.
