I have designed a DAC which is based on the PCM1794A and WM8804 chip.
The sound and performance are absolutely stellar.
THD+N: .0005%
SNR A-Weighted: 120dB
Frequency Response: DC - 30khz (-.5dB at 30kHz)
Noise Floor: -140dB
Power Input: 80-264VAC or 115-370VDC
Audio Input: S/PDIF coax or...
I am just wondering if there is anybody here that has had this issue with their circuits. Also how likely is it that this effect will add distortion/noise to the output of an audio amplifier even if it is not used in the audio path but only for decoupling purposes of MOSFETS, op amps, and also...
Hello,
I am hoping that somebody can help me out.
I am trying to simulate a power supply in Ltspice and I am having a problem
This power supply is a zero voltage switching isolated full bridge converter.
It take 18-30Vdc in and outputs 165V at 120W (0.7A)
The problem that I am having is...
It is unregulated just has 50% duty cycle all the time. The input voltage is always 15V and the transfomer is is 1 to 16 so we always should get 250V total on the output or + and - 125. And we do when the thing is loaded. The problem is only at light loads as you say. But how do we stop the...
Hello.
We have a full bridge power supply. And the secondary side of the transformer rings pretty heavily with low load and no load conditions. What is a good snubber/clamp design that can be used here that does not dissipate large amounts of power. (see attached image).
Here are some of the...
This i know that is the reason behind this post.
I have a circuit like this (see attachment) but how do I make the frequency variable over some predetermined range like +-10%
Thanks
I have a square wave with a variable frequency between 300khz and 360khz (Using LMC6908) that i need to convert into a triangle wave.
What is the best way to perform this task to keep the peak to peak voltage of the triangle wave constant.
Also my square wave is between 0 and 5V while my...
I forgot the second part of the question which is more important. How do I measure the DC on the line. It is quite difficult to filter out out 100Vrms signal.
Thanks;
Hello,
I have a 100Vrms AC signtal that varies in frequency from 40hz to about 15khz. I need to add a DC current (5V@5mA max) to this signal what is the best way of going about to do this. The signal is single ended and swings between +-141V around ground.
Help is much appreciated.
Thanks;
Leo
