The TLVx376 family represents a new generation of low-noise operational amplifiers with e-trim, offering both excellent dc precision and ac performance. Rail-to-rail input and output, low offset (125 µV, maximum), low noise (8 nV/?Hz), a quiescent current of 1. 2 mA (maximum), and a 5.5-MHz bandwidth . . . The TLVx376 family represents a new generation of low-noise operational amplifiers with e-trim, offering both excellent dc precision and ac performance. Rail-to-rail input and output, low off.......

The following discussion informs us regarding how to select the right power supply for a car amplifier which needs to be operated at home. The questions were raised by Mr. Gyaneshwar Singh. Thanks for creating awareness on your own concept and resolving problems of others. I am music lover requiring high bass with soft treble. . Considering my requirement, I had initially planned to get an ampl.......

Here the schematic design diagram of 600V power supply for QRO HF amplifiers. Amateur Radio Transmitters working with valves such as 807 or1625 operates properly using a plate voltage in between 600V to 700 Volts. The circuit described below is actually a full wave voltage doubler. The output voltage is twice the input voltage. For 230V AC input the output is going to be close to 600 Volts. Resister R1 is applied .......
