Build 32 Watt Amplifier Circuit Using by TDA2050V

Build 32 Watt Amplifier Circuit Using by TDA2050V. A 32 Watt per channel stereo power amplifier made using the TDA2050V monolithic integrated circuit.  32 Watt Amplifier Circuit Diagram Notes: This circuit is for a 32 Watt stereo audio power amplifier using the TDA20501. With a dual 22 Volt supply this amplifier can deliver 32W into 8 ohm loudspeakers. Moreover, the TDA 2050 delivers typically 50W music power into 4 ohm load over 1 sec at VS= 22.5V and f = 1KHz. The amplifier is cased as a Pentawatt package see pinout below: This is a power amplifier and requires 200mV RMS for full output. Voltage gain is 30.5dB with resistor values shown. Closed loop gain is set by Ratio R1/R2. Increase R2 for less gain and vice versa. Power bandwidth is 20Hz to 80KHz. R3, C3 and R6, C11 form a zobel network to prevent high frequency instability. The speaker is direct coupled, therefore no expensive large value electrolytics are needed and the bass will be crisp and clean. It is advisable to plac...

Adjustable Symmetrical Power Supply by LM317 and LM337

The circuit was designed to provide an adjustment with a power supply that is symmetrically designed while providing a voltage range of 1.25V to 30V at 1A current. Terminology LM317 – an adjustable 3-terminal positive voltage regulator capable of supplying in excess of 1.5A over an output voltage range of 1.2V to 37V and requires only two external resistors to set the output voltage due to its internal current limiting, thermal shutdown and safe area compensation, making it essentially blow-out proof LM337 – an adjustable 3-terminal positive voltage regulator capable of supplying in excess of 5A used as battery chargers, constant current regulators, and adjustable power supplies due to its features such as protected output from short circuit, product enhancement tested, current limit constant with temperature, guaranteed thermal regulation, adjustable output down to 1.2V, guaranteed 5A, and guaranteed 7A peak output current Circuit Explanation The circuit will serve as a voltage conv...

USB 5V to 12V DC DC Step Up Converter by LT1618

This is a 5V to 12V DC-DC step-up (boost) converter circuitry that is especially ideal for the USB powered applications. First of all a USB port has two current supply modes. Before detecting the connected device, it supplies maximum 100mA to the load. After recognizing the device, it increases the output current up to 500mA. In this circuit, controller (LT1618) also provides two input current modes. 100mA and 500mA input modes can be selected by the user. USB 5V to 12V DC-DC Step-Up Converter by LT1618  Output currents are limited due to the increased potential difference at the output. When the demand of the load increases, output voltage will start to decrease. For example, if the circuit operates in the 100 mA input mode, when the load is 35 mA, the output voltage will be kept at 12V. But if the load increases to 50 mA, output voltage will reduce to 8V to maintain the constant 100 mA input current.

New Nexus 10 2 2013 to be manufactured by Asus

  Asus will produce the nex Nexus 10 2 (2013 edition) according to new rumours The new Nexus 10 (2013 edition) will be made by Asus, a new screenshot has revealed. The pictures, revealed on Geek.com and presumably from a retailer's stock listing shows the Nexus 10 16GB with the brand listed as Asus, rather than Samsung that manufactured the original Nexus 10. Asus was responsible for making the first and second-generation Nexus 7 tablets and it seems Google was so impressed, it chose the Taiwanese company to make the bigger tablet too.  However, GSMArena says the source is pretty questionable because placeholder numbers are listed in the product's dimensions. Very few specs of the Nexus 10 have leaked thus far, although it's thought the next-generation Nexus 10 will feature a higher-resolution display and will launch on Android 4.3, just like the Nexus 7 2 (2013). There will also probably be a better, higher-powered processor - possibly the same...

Relay Switch Activated by Tone and Signal

This is a simple project of Relay Switch Activated by Tone and Signal circuit diagram.The essence of the circuit is for the input of tone and signal to provide an activation for the relay switch. Relay – an electrically operated switch where the current flowing through the coil of the relay is creating a magnetic field which attracts a lever and changes the switch contacts, thereby making its state open or close BC214 – a complementary silicon planar epitaxial transistor used in AF small signal drivers and am1 as well as for low noise preamplifier applications due to its feature of good linearity of DC current gain LM741 – a general purpose single operational amplifier with features such as offset null, compensated internal freq uency, voltage range with high input, good stability of temperature, and protected from short circuit The use of relay will allow the circuit to switch from one condition to another. It can also be referred to as a form of an electrical amplifier since it is a...
