The model accurately predicts the TID response of board-level designs with a 79X increase in simulation speed when compared to the SPICE model for the example application of a Schmitt trigger ...

To see why, we’ll dive back into the theory of operation of the op amp, considering closed-loop response compared with open-loop response. If you want an audio pre-amp circuit using an op amp with a ...

Analog Devices has created a fast power op-amp that can handle ±55V rails and ±1A outputs, with a digital control bus for setting internal parameters. Called ADHV4710, the output can swing ±52V with ...

Note that in the op amp shown in Figures 2 and 3, there are both positive and negative power supplies, whereas the circuit in Figure 1 uses just a positive supply. The circuit in Figure 1 is typical ...

I was pondering possible interfaces between a microcontroller and a 12 or 24V 5015 blower fan. The challenge is that the MCU can only drive 3.3 or 5V, while the blower needs needs a voltage as low as ...

Design Improvements If the heat dissipation is higher, increase the shunt resistor wattage. For selecting the wattage of the shunt resistor, Rw = I2R can be used, where Rw is the resistor wattage and ...

Positive Feedback in Op-Amp The non-inverting amplifier circuit can be modified a little bit to create a circuit that has positive feedback. The inverting and the non-inverting inputs of the op-amps ...

When selecting an operational amplifier (op amp), you have many parameters to consider. DC parameters such as input offset voltage and input bias current are easier to account for because they do not ...

In the last Circuit VR we looked at some basic op amp circuits in a simulator, including the non-inverting amplifier. Sometimes you want an amplifier that inverts the signal. That is a 5V input res… ...

For example, you could set the load resistance to 0.1 ohms. The simulator will dutifully show the op amp sourcing 25A of current through the load.
