Hello John W. I have uploaded the complete Robertugo/SwitchAna files from my personal archive. It appears to contain all that is needed for the 4051, 52 and 53 parts. I hope this helps. https://groups

John23 You could place a V source in series with one of the op-amp inputs. Set it to a few uV to see the effect of input offset on your integrator. Set the V source to the data sheet's maximum offset

If you have enough room to use a shunt cuicuit and one visible 20mA LED, then why not just use four identical visible 20mA LEDs in parallel. 80 mA current capacity and you don't have to design a shunt

LTspice caches information about symbols in the .ASC file. Open test.asc in a text editor and search for "Altium". You will see the old, bogus, no longer applicable "M:\Altium" information. To fix it,

Be very careful to fully understand Figure 6-16 or Figure 6-18 in TI's TL431 datasheet, whichever applies to your specific part. According to Figure 6-16 and Figure 6-18 both, the circuit given in the

Hello All, I uploaded a scan of the Motorola CMOS Databook Series C p3 (1978) in case anyone is interested. I know Andy is concerned about the groups drive space usage so I will leave it up for a few

Hello All, Andy wrote: Then consider how manufacturing drifts over time. Like it or not, in 2024 they don't make them like they used to in 1975. I beg to differ. A great many of today's popcorn diodes

Hello All Any diode exhibits the varactor effect. The capacitance of a reverse biased diode decreases with increased reverse bias voltage. Increased reverse bias expands the depletion region of a diod

Hello All, I did a little research to make sure before stating, MMBD4148T1G is not a varactor diode. It is the ubiquitous 4148 switching diode. Also quite curious is the MMSD4148 model included with L

Nara962, The upper limit of your coil inductance can be determined by creating a series R/L circuit pulsed at coil voltage given in the datasheet and permitted to flyback into a diode. The resistance

O.K. I have prepaired my meal of crow and am now prepared to eat it. Andy is correct. I was wrong. My error was not realizing that an RMS voltage value will produce an RMS current value. Assuming a 1

Javier, Asking for the RMS value of a pulse wave is simply not a correct question to ask. Although mathematically correct the answer is meaningless. RMS applies only to waveforms that do not spend an
