Frequently Asked Questions Q: Is The Magnification Fixed? How To Adjust? A: The Default Magnification Of The Module Is 33 Times. If You Need To Adjust The Magnification, You Can Only Replace The Resistor On The Board. The Resistance Package Is 0805. The Calculation Formula Is Given In The Parameter Details. Q: Can The Module Directly Drive The Coil? A: The Module Can Drive The Coil, But The Coil Internal Resistance Is Required To Be Greater Than 4 Ohms. If It Is Less Than 4 Ohms, A Series Power Resistance Is Required, Otherwise The Module May Be Damaged. Q: Can The Module Amplify Square Wave Or Pulse? What Is The Module Bandwidth? A: The Module Can Amplify Low-Frequency Square Waves Or Pulses. Because It Is An Audio Amplifier, The Total Bandwidth Is Not High. Signals Within 100K Can Be Amplified. The Module Is Compatible With Dc Input. Q: Can The Module Be Enlarged 1: 1? That Is To Only Amplify The Current? A: The Module Can Support 1: 1 Amplification. You Need To Modify The Resistance Configuration Magnification Yourself. It Is Not Recommended To Directly Configure The Op Amp Follow Mode. This Is Easy To Self-Excitation. It Is Recommended To Change To Resistance Attenuation First, And Then Operation Amplification. The Total Gain Is 1 That'S It. Q: Why The Input Sine Wave Output Is Square Wave? What Is The Output Current? What Is The Output Power? A: Generally Speaking, The Input Signal Is Too Large, And The Op Amp Is Amplified To The Cut-Off Distortion, Which Is The Square Wave, Or The Supply Voltage Is Not Enough. Can Reduce The Input Signal And Increase The Supply Voltage To Solve. The Output Current Of The Module Is Determined By The Output Voltage And Load. L = Uout / R. Similarly, The Output Power P = U * 1 Is Also Determined By The Output Voltage And Load Resistance. Heat Dissipating Silicone Grease And Air Cooling Can Be Added At High Power Input.
