Mic Preamplifier Circuit based TLC251

Here the schematic diagram of mic preamplifier which build based on operational amplifier TC251. The TLC251 is operating in low bias. The circuit works with only 1.5 V supply draws electric current of only 10 mA, so the battery operation will be prefered.Circuit frequency response is 3dB, 27 Hz to 4. 8 kHz.

Experimental QRP transmitter by UB5DT, \"Radio\" magazine, April 1967

-Radio- magazine cover, April issue, 1967 For those of my friends tube radio builders, who asked me about -Soviet novice transmitter-, -XUSSR QRP TX- (as it pronounced in telegraph), -something authentic, but not too complex- etc, such a RIG should be a good choice - easy to build and clearly adjustable design, small amount of wid.......

Variable DC Power Supply 3-24V / 3A

Variable DC Power Supply 3-24V / 3A circuit diagramThis is the variable DC power supply circuit. This power supply has regulated output, can be adjusted from 3 to 25 volts and the current output is limited to 2 amps as shown, however it may possibly be improved up to 3 amps or more by applying a smaller current sense resistor (0. 3 ohm). Voltage regulation is controlled by 1/2 of a 1558 or 1458 op-amp. The 1458 m.......

Op-amp | Block Diagram | Characteristics of Ideal and Practical Op-amp | Best Engineering Projects

What is an OP-AMP? An operation amplifier (Op Amp) is basically a multistage, high gain (Av>105) direct coupled amplifier with two differential inputs and a single ended output and which uses feedback to control its overall response characteristics. It may be used to perform numerous linear operations and some nonlinear operations. An important feature of operational amplifier is that by simply changing the feedback impedance, its operation may be altered.A modern Op Amp uses integrated circuit .......

LTC6258 - 1.3MHz, 20?A Power Efficient Rail-to-Rail I/O Op Amps - Linear Technology

The LTC®6258/LTC6259/LTC6260 are single/dual/quad operational amplifiers with low noise, low power, low supply voltage, and rail-to-rail inputs and outputs. They are unity gain stable with or without capacitive loads. They feature 1. 3MHz gain-bandwidth product, 0. 24V/μs slew rate while consuming only 20μA of supply current per amplifier operating on supply voltages ranging from 1. 8V to 5. 25V. The combination of low supply current, low supply voltage, high gain bandwidth product and lo.......

Hobby Circuit - HIGH PASS ACTIVE FILTER COLLECTION __ Circuit s designed by David A. Johnson, P.E.

This is a collection of inverting and non-inverting active high pass filter circuits.  I included one, two three, four and six pole filter circuits.  You can change the component value ratios shown to achieve any frequency cut-off you may need. The circuit does not specify an operational Amplifier. The circuits should be used to select the needed resistor and capacitor components for a particular frequency knee and slope........
