Even in real op-amps, the datasheet often guarantees only aminimumopen-loop gain, but not a maximum. You can’t and shouldn’t design a circuit relying on knowing the exact value of the open-loop gain of an op-amp. It can be hard to think about infinities! One helpful mental trick...
Philips Semiconductor developed the I2C bus to connect integrated circuits domiciled on a single printed circuit board. The evolution of the standard has since ensured that the bus is used in off-PCB applications. In this case, galvanic insulation ca...Read More Würth Elektronik enters the smart...
Common mode capacitance Rf1 Vcc+ Ccm1 Rs1 - TS462 + Rs2 Ccm2 Rf2 Vcc- It is recommended to place the same low-path filter on each input of the op amp, in order to equilibrate the two inputs. Unlike an instrumentation amplifier, the ...
In principle creating a miniaturised version seems straightforward, by integrating all the photodiodes onto one printed circuit board (PCB); and the first stages of optical processing to obtain I, p and c could happen onboard. An alternative could be a complementary metal-oxide-semiconductor (CMOS...
It preserves the tone shaping and character of the best of Rupert Neve's circuit designs over the years while making it more accessible to those who can't fit a large format console in their bedroom (hey, we can all dream, right?). ...

- Why use diodes instead of just using another value for R8 and no diodes, that would give the same operating point when the output of the Opamp is low ? Speaking of playing with component values, I doodled this part of the circuit in LTSpice, which simulates without any problem, of ...
Due to the acoustic short circuit between front and rear radiation of drivers on an open baffle it becomes especially important to find a woofer driver which is capable of large excursions without non-linear jumping effects and without air turbulence noise. Figure 13. 4.1.1 Dipole woofer The wo...
Yep, Matt always has a lot of work coming through, so re-patching his whole chain for a whimsical experiment wasn't a reasonable request to my mind. That being said, the console isn't bringing much to the equation, and it's equally present in both samples. I believe the circuit is ...
So as the diode turns on, the gain of the opamp stage changes, going down to just over 1 if the diode can be considered a short circuit compared to the 4.7 K resistor on the (-) input. Even if the Drive control is set for a gain of 100, the diodes conducting cause the gain to...
