Re: best books
Best books? That's a matter of each ones preference. For analog design and some microprocessor circuits I have a list of books on my website at https://MasteringElectronicsDesign.com The books are under "Expand your knowledge" section.
Multisim has a Component Wizard under Tools. You start the wizard, then click on simulation only, then choose the number of pins (5 in this case), choose a symbol (an op amp, copy from database). At model, start Model Maker. Choose Operational Amplifier and then fill up a table with the...
This thread goes into the wrong direction and the conclusion is false.
LvW is right. There is no such rule in a simulator to add a resistor in the non-inverting input. We might add a small resistor to help the simulator converge to a solution but this is not the case. The rule applies in...
Why do you need to represent an ideal fully differential amplifier with Voltage Controlled Current Sources (VCCS)? You can use a Voltage Controlled Voltage Source (VCVS), which is fully differential (in and out). Maybe you need to upload a block diagram of your Multiplying DAC, so that we can...
This would work with a few remarks:
1. LM358 is not a rail-to-rail OP Amp so you will need to power it at minimum 6.5V to have a range of 0.5V to 4.5V in the first Op Amp.
2. 0.1uF cap at the second Op Amp output is a no-no. The second Op Amp is prone to oscillate. Insert a small resistor...
OPA4658 output is bipolar, while the input of 74HCT04 is unipolar. So, make sure you limit the op amp output voltage to the positive region.
Even so, you cannot just power the opamp between 0 and 5V, because the opa4658 output low level is about 2.3V from rail so the HCT04 will not be able to...
It depends on what you consider processing. The Op Amp will consider the digital signal as analog one. If the Op Amp receives a 0...5V signal for example, it can amplify it, attenuate it, add another signal to it, subtract another signal, filter it, etc, whatever an Op Amp can do to a signal...
XFG1 is bipolar. You need to ground the middle output called "common". The setting is 100mVp, which means that, after connecting common to ground, you will have an amplitude of 200mVp-p (peak to peak).
Re: LM675T Problem
Take a look at its datasheet, here:
**broken link removed**
It needs a negative supply as well if you are to bring 0V in its input as your drawing shows. On page 2 you can see that it has a typical gain of 90 dB. This is a gain of 35000, so the output will quickly hit the...
The easiest way is to split it in sub ranges, 2.5k, 25k, 250k.
If this is not acceptable, the solution is more elaborate. You need at least a 12-bit ADC to cover that range. Assuming a reference voltage of 2.5V, the ADC will measure between 10.4mV to 2.5V depending on the resistor to be...
multiple 0-10v dc circuit
... or you can use a 50mA capable Op Amp like the Analog Devices' AD817. 50mA output is minimum. It can do more. Careful with the power dissipation though.
