What is the value of the output resistor an ideal op amp?

What is the value of the output resistor an ideal op amp?

zero
The current flow into the input leads is zero, so the input impedance of the op amp is infinite. The output impedance of the ideal op amp is zero.

What will be the output if supply voltage is +/- 15v?

I got this equation for a summer circuit output voltage fed into an inverting opAmp. Both opAmps have supply voltage of ±15 V. Vout = -6*V1-30*V2-60*V3. I got Vout = -390 mV. I know that the ± 15 volts is there to tell a range of possible voltages; Vout cannot be out of the supply range.

How do you calculate feedback resistor?

The feedback resistor Rƒ sets the operating voltage point at the inverting input and controls the amount of output. The output voltage is given as Vout = Is x Rƒ. Therefore, the output voltage is proportional to the amount of input current generated by the photo-diode.

What is the maximum limit of the output voltage of an op amp?

A typical op-amp has an output voltage limit somewhere in the ±1 V to ±3 V range. Often the output is more limited towards one power rail than the other — it might be +2.7 V and -2.9 V, for example.

What should the resistor value of an op amp be?

Resistor values should stay within the range of 1–100 kΩ. The lower limit avoids excessive current draw from the op amp output, which is particularly important for single-supply op amps in power-sensitive applications. Those amplifiers have typical output currents of between 1 mA and 5 mA.

How is the gain of an op amp calculated?

This calculator calculates the gain of a noninverting op amp based on the input resistor value, R IN, and the output resistor value, R F, according to the formula, Gain= 1 + RF/RIN . To use this calculator, a user just inputs the value of resistor, R IN, and resistor, R F,…

How is the output voltage of an inverting op amp determined?

The feedback resistor Rƒ sets the operating voltage point at the inverting input and controls the amount of output. The output voltage is given as Vout = Is x Rƒ. Therefore, the output voltage is proportional to the amount of input current generated by the photo-diode. Inverting Op-amp Example No1

What is the Max current of an op amp?

If the max current of the op-amp is 5mA (have to check datasheet), and the max voltage was 5V, I would choose R19 to be 1k. That way if the user attached R19 to ground it would draw 5mA and not damage the amp.
