Introduction
The IRAUDAMP12 reference design is a two-channel, 130W/ch (4Ω/±31V; no heatsink)/ 160W/ch
(4Ω/±34V; *with heatsink) half-bridge Class D audio power amplifier. This reference design
demonstrates how to use the IR4301 IC, implement protection circuits, and design an optimum PCB
layout using PowIRaudio integrated Class D IC. This reference design does not require heatsink or
fan cooling for normal operation (one-eighth of continuous rated power).The reference design
provides all the required housekeeping power supplies for ease of use. The two-channel design is
scalable for power and the number of channels.
Applications
AV receivers
Home theater systems
Mini component stereos
Powered speakers
Sub-woofers
Musical Instrument amplifiers
Car audio amplifiers

Test Procedures
Test Setup:
1. Connect 4-250 W dummy loads to output connectors (J3 and J4 as shown on
Figure 1) and parallel it with input of Audio Precision analyzer (AP).
2. Connect Audio Signal Generator to J6 and J5 for CH1 and CH2 respectively (Ap).
3. Set up the dual power supply with voltages of ±15V~±31V (up to ±34V with
heatsink); set current limit to 5A.
4. Set switch S1 to middle position (self oscillating).
5. Set volume level knob R130 fully counter-clockwise (minimum volume).
6. Connect the dual power supply to J7. as shown on Figure 1
Power up:
7. Turn ON the dual power supply. The ±B supplies must be applied and removed at
the same time.
8. Red LED (Protection) should turn on almost immediately and turn off after about 3s.
9. Green LED (Normal) then turns on after red LED is extinguished and should stay on.
10. Quiescent current for the positive supply should be 60mA 10mA at +31V.
11. Quiescent current for the negative supply should be 80mA 10mA at –31V.
12. Push S3 switch (Trip and Reset push-button) to restart the sequence of LEDs
indicators, which should be the same as noted above in steps 9-10.
Functionality Audio Tests:
13. Apply 1V RMS at 1kHz sinusoidal signal from the Audio Signal Generator.
14. Turn control volume up (R130 clock-wise) to obtain an output reading of 250Watts.
15. For all subsequent tests as shown on the Audio Precision graphs below (Figure 3-
Figure7), the measurements are taken across J3 and J4 with an AES-17 Filter.
Observe that a 1 VRMS input generates an output around THD+N=1% power level.
16. Sweep the audio signal voltage from 15 mVRMS to 1 VRMS
.
17. Monitor the output signals at J3/J4 with an oscilloscope. The waveform must be a
non distorted sinusoidal signal with input signal below 1Vrms.
