Category: Inside Circuits Views: 2793 Rank: 10 This Circuit is based on the LM3876. A 11-pin plastic package IC with high performance audio power amplifier, an output mute function which can be used to eliminate switch-on and switch-off `thumps` to the loudspeaker load. It is capable of delivering 40W continuously into 8ohm load, and is fully protected using established techniques. The output stage is protected against short circuit to ground or either supply rail. Protection against transients from inductive loads is also provided at the output stage via internal clamp diodes.  The device also contains thermal shut-down protection which comes into operation if the chip temperature exceeds its safe operating range, and under-voltage shut-down in the event it to operate properly. The LM3876 is internally compensated and stable fro Datasheet file1: Click here to download LM3876.pdf datasheet.
Related circuits Transistors Q1 and Q2 amplify the incoming signal, and the gain is such that the input will overload when used with an electric guitar. RVl adjusts the amount of feedback present, and hence voltage gain. The output is, therefore, a squared version of the input signal Digital Voice Recorder/Playback (UM5100) This Circuit is based on the UM5100 which can record speech into a digital memory and then play it back. The device is designed to be used directly with static RAM's up to 256K bits, or with EPROM 's or ROM's for playback only. High quality voice reproduction is possible and note that it is not a... The circuit essentially provides low-frequency boost below 318 Hz and high-frequency attenuation above 3150 Hz. When the mains voltage is present at the input terminals, the transistor in the optocoupler is on, T1 is off, and s 4093 Cmos Astable Oscillator Circuit Two gates of the Quad 4093 are used to make an oscillator. R,t: can be from about 5 kft to around 10 . Cx can be from about 10 pF to many , the limit being set by the leakage of the capacitor. This circuit outputs a TTL-compatible - pulse whenever the signal falls within the limits set by potentiometers An infrared LED and a phototransistor are used for each eye. Half of a 556 timer IC (ICl-a) functions as an as table multivibrator oscillating at a frequency of about 1 kHz. That IC drives transistor Ql which in turn drives the two infrared LED's, LED1 and LED2. The right eye is composed of LED1... This is a simple headphone amplifier. You can use any NPN transistor.
