Circuit Audio Stereo power amplifier LM4755 11W with Mute

The internal mute circuit and pre-set gain resistors provide a cost-effective design solution. Output power specifications at both 20V and 24V supplies, along with a low external component count, offer significant value to consumer electronic manufacturers for stereo TV and...

5 Watt Class-A Audio Amplifier Circuit

This solid-state push-pull single-ended Class A circuit is capable of providing sound quality comparable to valve amplifiers, delivering an output power of 6.9W measured across an 8 Ohm loudspeaker cabinet load. It exhibits lower total harmonic distortion (THD), higher input...

Audio Subcarrier Oscillator

A single integrated circuit (IC) provides all amplifiers: the 74HC04 Hex Inverter, which is a digital component. The second oscillator synchronizes to three times the frequency of the first oscillator, thereby tripling the frequency modulation (FM) deviation. Utilizing the lower...
