R4 is the input resistance. Your email address will not be published. Sir, can i power this circuit using 12 0 ……. Use of the information on this site may require a license from a third party, or a license from TI.
LM Gainclone Amplifier
Our customer would like to replace from LM to LM The circuit includes an auto ranging as well as reset switch and produces very accurate and stable readings. Other features of LM are output to ground short circuit protection, input mute function, and output over voltage protection, etc. The output waveforms can be both amplitude and frequency modulated. I used a cut-down P88 preamp PCB because I only wanted one preamplifier stage, but the entire board can also be used.
Quiescent current of LM is around lm387. S1 is the mute switch. Do not ever allow the heatsink to short to ground.
Dec 22, 2: The bipolar electrolytic capacitor C7 is the input DC decoupling capacitor. The circuit includes an auto ranging as well as reset switch and produces very accurate and stable readings.
We are glad that we were able to resolve this issue, and will now proceed to close this thread. Kind regards, Hirotaka Matsumoto. The meter is a perfect addition to any power supply, battery chargers and other electronic projects where voltage and current must be monitored.

Arduino Prototype uses all standard through-hole components for easy construction, two of which are hidden underneath IC socket. Never run the amplifier without a heatsink attached to the LM chip s 3. Do you have another question?
56W LM3886 / LM3876 Gainclone
Ml3876, it has been corrected…. If you are powering more than 2 channels a VA or VA transformer is recommended. Dec 22, 3: Headphone amplifier is small enough to fit in Altoids tin llm3876, and thanks to low power consumption may be supplied from a single 9V battery. It’s small, power efficient, yet customizable through onboard 2 x 7 perfboard that can be used for connecting various sensors and connectors. R3 is the mute resistance which allows 0.
LM3886: replace from LM3876 to LM3886
This was actually the intent of the original designers. Applications of LM are component stereo, compact stereo, surround systems, self powered speakers, etc. The LM can deliver 50watts of output power into an 8 ohm loudspeaker. It is an irreplaceable tool for troubleshooting and repairing electronic equipment by determining performance and health of electrolytic capacitors.
