4 / 5 page EV0041 MP8040 Full Bridge or Single Ended Audio Amplifier EVALUATION BOARD EV0041 Rev 1.4_8/1/05 Monolithic Power Systems, Inc. 4 Monolithic Power Systems Operation 1. The EV0041 comes configured as a stereo single ended audio amplifier (EV0041A). 2. To configure the board as a full bridge circuit (EV0041B), short R4, R7, R9, remove C4, C7 and stuff C12 with a 0.47 µF capacitor. 3. Connect the audio inputs to the IN pins as shown in Figure 5. 4. Connect speakers to pins 1-4 as shown in Figure 5 for single ended configuration. Use pins 2 and 3 for bridged circuit. 5. Connect the power supply to the VIN terminals as shown in Figure 5. 6. SHDN enables/disables the MP8040. Drive SHDN low to turn on the MP8040, drive it high to turn it off. If not used connect SHDN to GND. 7. A low output at FLT indicates that the MP8040 has detected a fault and has shutdown. 8. The DR pin is an optional fixed 5V voltage output capable of driving a 1mA load for external circuitry.
