LM4702 DATASHEET PDF

Mezragore Transistors Q1 and Q2 are populated at the bottom of the PCB and physically make contact datadheet the aluminum bracket as well as the heatsink of the power output transistors. Welcome to our site! If you obtain similar DMM readings, you may proceed with music test. Project 43 BuildAudioAmps Do not connect any load or loudspeaker at the outputs of the amplifier. It also provides inverse thermal tracking to maintain the bias level as the output stage temperature changes. As far as hook up just use it with one output.

Everything else is what is attached to it. Use a heat sink for the LM They will give you far more control and function than you could ever build for the same price. I would just put a log pot on the inputs. One question i do have though is. Replacement Transformer Started by ncag Today at 7: The DMM tells you the bad news first and when the inevitable happens you immediately switch OFF the power supply and recheck the assembly.

Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets. Dagasheet not connect dtaasheet load or loudspeaker at the outputs of the amplifier. The DMM across the fuse terminals should read less than 30mA. Thread starter discostuee Start date Mar 30, All of the passive components used in the prototype model dattasheet standard, commercially available parts.

The leads should be shorted. The DMM tells you instantly if there is something wrong with your printed circuit board assembly. These components are not easy to find. Insert a jumper or shunt dagasheet J1 and J2 inputs of the amplifier. TheSchematic Diagram Figure 2. The picture above shows a DC offset voltage for channel 1 at 3. The ability to set lower bias levels on the LM means less wasted power and less heat. To participate you need to register.
