Making a Home Theater System Using IC TDA 7560

The TDA7560 is a breakthrough BCD (Bipolar / CMOS / DMOS) expertise class AB Audio Power Amplifier in Flexiwatt 25 package designed for superior power car radio.
The fully complementary P-Channel/N-Channel output structure makes it possible for a rail to rail output voltage sway which, fused with high output current and minimized saturation losses sets new innovative power referrals in the car-radio field, with incomparable distortion performances.

DC OFFSET DETECTOR

The TDA7560 combines a DC offset sensor to prevent that an anomalous DC offset on the inputs of the amplifier might be multiplied by the gain and lead to a risky significant offset on the outputs that may result in speakers harm for overheating. The feature is enabled by the MUTE pin and operates with the amplifier umuted and without signal on the inputs. The DC offset identification is signaled out on the HSD pin.

STAND-BY AND MUTING STAND-BY and MUTING facilities are both CMOS-COMPATIBLE. In lack of genuine CMOS ports or microprocessors, a direct connection to Vs of these two pins is suitable yet a 470 kOhm equivalent resistance need to present between the power as well as the muting together with stand-by pins.

NE566 Function Generator Circuit Diagram

The NE566 Function Generator is a Voltage-Controlled Oscillator of exceptional linearity with buf fered square wave and triangle wave outputs. The frequency of oscillation is determined by an external resistor and capacitor and the voltage applied to the control terminal. The Oscillator CAN be programmed over a ten-to-one frequency range by proper selection of an external resistance and modulated over a ten-to-one range by the control voltage, with exceptional linearity.

Transceiver Homebrew QRP SSB 80M Band

Radio communication transceiver is a radio transmitter at the same time the plane doubles as a radio receiver used for communication purposes. It consists of the transmitter and the receiver are assembled in an integrated way. In mulamula generation, the transmitter or receiver or transmitter and receiver sections are assembled separately and is part of a stand sendirisendiri and can work well sendirisendiri Currently employed both parts are integrated in turn. Aircraft simple transmitter consists of an oscillator generating radio vibration and this vibration after vibration boarded with our voice, in a technique called dimodulir radio, then by the antenna is converted into radio waves and transmitted. As we know that the sound waves we can not reach long distances, although its power is quite large, while the radio waves with a relatively small force can reach a distance of thousands of kilometers. In order for our voice can reach a far distance, then our voice superimposed on radio w...
