Hello Fellow Electronics Enthusiasts,
I have a couple of AD822 single supply op amps. I wanted to clear one thing that is if i connect both the inputs of the op amp to the ground i still get a voltage of 5mV at the output. Is this normal or is there a problem with my ICs. Should the voltage be...
I'm coming from a programming background and although I'm doing more electronics recently I'm still very much learning.
I'm using a bluetooth module (this one **broken link removed**)
It has an LED function but it's really annoying. It blinks quickly when bluetooth is not connected, and blinks...
Hi all i have a problem with a LM741 op-amp,
when calculating the output voltage i should have when inputting 12vpp using the formula Vo = Vi(1+Rf/Ri) and the values being vi = 12 rf = 6k Ri = 1.5k i should be having an output of 60v, but when building and simulating my design i only have...
Hi,
Recently I watched an old EEVBlog episode (#102) where Dave discusses and builds a basic constant current load. To try it out, I quickly built the circuit on a breadboard and got curious to fully understand how it works. For the op-amp I used the LM2904 and for the mosfet a STP60NF06, then...
Each of the op amps shown in the attached circuit diagram is powered from differing rails (+, gnd and gnd, -) to produce two identical, but DC shifted, outputs.
In addition, the input signal is referenced to the negative rail instead of ground. There is a reason for this relating to balanced...
Hi
I have occasion to work on aviation headsets occasionally and rather than buy an aircraft intercom to just use on the workbench, I am thinking there might be an easy solution with parts on my bench. The mics are called amplified electret.
Spec sheet of a typical set is here...
Hello dear friends,
The following image is that of a Data signal, one waveform is used to represent logic level 1 and other 180 degree phase shifted waveform represents logic 0. Can someone please provide some input on how I may be able to generate the following waveforms on a micro-controller...
Hello all, I'm looking for a component recommendation for a unity gain analog inverter. I have available a regulated 5v DC supply and a stable ground supplying various sensors whose outputs serve a sealed black box computer. The computer generates various control signals up to 12 volts DC, it's...
