I'm trying to convert 11-16 Vdc to 5 Vdc @ 3 A to run an array of low-impedance ratiometric sensors. The outputs are going either directly into an ADC or amplified through an instrument amplifier. ...
I have a signal that should have this theoretical shape: The signal I am receiving experimentally has the following shape: And here is a plot that better shows the shape of the waveform (I have ...
I'm powering a 12 V computer fan with a simple 7810 circuit shown here: When the fan is connected to the regulator, on the output I get this wave: When I zoom out in time, I get something that ...
I am working on an audio circuit featuring the MOS Technology 6581 SID. The circuit works on a solderless breadboard with acceptable but still quite noticable noise. I am now going to design a PCB, ...
I've developed a circuit for my model aircraft, which requires 3.3V @ 100mA. My aircraft uses a 3S LiPoly, which ranges from 9V - 12.6V. When the motor is off, the 3.3V supply is good; very low ...
I'm using an LM317T to regulate 5V to 3.38V for a microcontroller. R1 is 330 ohms and R2 is 560 ohms. There is no input capacitor and the output capacitor is a 470µF 25V, because I had that value in a ...
I've got a battery powered synth that uses two 9v batteries to make a split rail power supply (±9 and ground). I'm trying to use a regular AC-DC power adaptor to replace the batteries. The adaptor ...
