Here the circuit diagram of 25 watt Hi-Fi (high fidelity) audio amplifier that build based on single power amplifier IC LM1875 that should be run using heatsink attached on its….

…When the switch is released C3 begins a slower discharge through R7 and R3 with a time constant of about 5 seconds. The op amp is set up as a…

…Circuit Notes: This simple circuit uses a 741 op-amp in differential mode as a continuity tester. The voltage difference between the non-inverting and inverting inputs is amplified by the full…

…sound is detected by ultrasonic receiver. The signal is then amplified by IC1:A and IC1:B. IC1:A is selfbiasing via C2 & R5. The time constant of the first amplifier is…

…generator. Op-amp A2 operates as an integrator, whilst op-amp A3 runs as being a comparator. A2 and A3 together with each other perform as being a “wandering voltage generator” op-amp….
