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.

TDA2030 complete tone control

At this time I present a series of amplifiers that use IC TDA2030, but this series is equipped with a tone control. Tone controls include Bass, Treebel, and Volume. Power amplifier and tone control has been put together in a single PCB. As well as its power supply circuit was also used as one with the power amp, and tone control. Making it easier in the installation and will look neat. Schematics Layout PCB PCB design This amplifier is a mono amplifier type, can be modif for guitar amplifiers. If not coupled amplifier (mic preamp) then you must deactivated potensio treble and bass, why? because if not using a mic preamp and still maintain potensio treble and bass sound input (input) from the guitar will not or the maximum discharge is not tight on the speakers. So you must deactivated a way to decide which directly connected capacitor with the tone control circuit, and capacitor were connected directly to potensio volume and input jack.

PID instruction in Allen Bradley PLC Closed Loop Control

PID instruction in Allen Bradley PLC [Proportional/Integral/Derivative] Closed Loop Control For Processor SLC 5/02SLC 5/03SLC 5/04SLC 5/05 MicroLogix 1200 and MicroLogix 1500 (A special PID file replaces the old integer file control block.) Description of PID in PLC This output instruction is used to control physical properties such as temperature, pressure, liquid level, or flow rate of process loops. The PID instruction normally controls a closed loop using inputs from an analog input module and providing an output to an analog output module as a response to effectively hold a process variable at a desired set point. The PID equation controls the process by sending an output signal to the actuator. The greater the error between the setpoint and the process variable input, the greater the output signal, and vice versa. An additional value (feed forward or bias) can be added to the control output as an offset. The result of the PID calculation (control vari...

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.
