1W stereo Headphone Amp (TDA2822)
A stereo power amp designed for use in portable players and radios. A 3V supply can be used to drive headphones providing 20mW in 32 Ohms per channel. A 9V supply will provide 1W in 8 Ohm per channel for...
Stereo Preamplifier and Bass-booster
This preamplifier was designed to cope with CD players, tuners, tape recorders etc., providing a gain of 4, in order to drive less sensitive power amplifiers. As modern Hi-Fi home equipment is frequently fitted with small loudspeaker cabinets, the bass...
Stereo Preamplifier Circuit (741)
The circuit operates using two 741 operational amplifiers and achieves a gain exceeding 20 dB in each channel. Utilizing a higher-quality op-amp can improve the noise figure and bandwidth. Additionally, the circuit features a sharp roll-off at 20,000 Hertz.
This circuit...
audio graphic equalizer circuit
A gyrator is a circuit that utilizes active devices and transistors to emulate an inductor. In this instance, the gyrator comprises a transistor in conjunction with resistors R1, R3, and capacitor C2. Alternatively, a unity gain operational amplifier could be...
Stereo Tv Decoder Circuit
Q1 is an audio amplifier, and U1 is utilized as a 31.5 kHz subcarrier, which is comparable to the 38 kHz FM multiplex. The pilot frequency is 15.734 kHz.
