4- Consider an OP amp connected to the inverting configuration to realize a closed-loop gain of -50 V/V utilizing resistors o f1 k2 and 50 kN. A load resistance RL is connected from the output to ground, and a low-frequency sine wave signal of peak amplitude Vp is applied to the input. Let the OP amp be ideal except that its output voltage saturates at +/- 10V and its output current is limited to the range +/-15 mA. For RL = 1 k2, what is the maximum possible value of Vp while an undistorted output sinusoid is obtained?

A certain op-amp has three internal amplifier stages with midrange gains of 30 dB, 40 dB, and 20 dB. Each stage also has a critical frequency associated with it as follows: fc1 = 600 Hz, fc2 = 50 kHz, and fc3 = 200 kHz. (a) What is the midrange open-loop gain of the op-amp, expressed in dB? (b) What is the total phase shift through the amplifier, including inversion, when the signal frequency is 10 kHz?

2. Suppose we have an op-amp that is powered by a ±15 V supply (assume Vout max is ±14V), and has a maximum output current of 50 mA. The maximum slew rate of the op amp is 107 V/s. In the circuit below where Vin=5sin(100t). a. What would the output voltage Vout be if the op amp were ideal? b. Compute and draw the actual output voltage if a load resistor of Rload=100 N is attached to Vout. Vin ww 1 ΚΩ ww 4 ΚΩ + +15V Op-Amp -15V Vout
