lm35dz temperature control schematic
lm35dz temperature control schematic The Lm35dz series are precision integrated-circuit temperature devices with an output voltage linearly-proportional to the Centigrade temperature. The LM35 device has an advantage over linear temperature sensors calibrated in Kelvin, as the user is not required to subtract a large constant voltage from the output to obtain convenient Centigrade scaling. 16f877 […]
1500W Power Amplifier Circuit Diagram
1500W Power Amplifier Circuit Diagram 1500W Power Amplifier Circuit Diagram This is a very high 1500W power amplifier circuit diagram by Rod Elliott. The circuit is built using 10 pairs of power transistor MJ15024 and MJ15025 (or MJ21193/MJ21194), then it will use 20 pieces of power transistor for final amplification.With very high power audio output, […]
