You finished an audio circuit. But the sound is too weak. Many people use LM386 to increase sound up to a speaker. Why should you do it too? Some said to try it now. But...it is better. If you read LM386 Datasheet before.
This is TDA2822 small stereo power amplifier. People like TDA2822. Me too. Why? Dual Amplifiers in one. With DIP-8 similar for LM368(Mono). Easy uses. Give power watts at 1W + 1W at 4 ohms speakers. It is enough. We are happy Listening in our corner. Relax... Start voltage supply of 1.8V to 15V. The wide a lot. Save energy with only 6mA, Min. The bandwidth expansion rates at 40dB 120kHz. Cheap and easy
Here is a LM1875 datasheet, used for a 20W audio amplifier on Class AB type. Voltage Gain is 90dB. Low Harmonic Distortion Noise is 0.015%, 1KHz, 8 ohms [...]
This is the CD4027 datasheet of dual J-K flip-flops are monolithic complementary MOS (CMOS) integrated circuits. Its internal structure consists of N- and P-channel enhancement mode transistors. Each flip-flop has…
