Question

TA Pass-off The purpose of this lab is to allow students to put into practice the principles learned in class regarding Operation Amplifiers PRE-LAB WORK Please do the pre-lab work Begin the lab by identifying below which of the given Op-Amps are inverting and which are non-inverting. After you have done this, analyze each of the Inverting and Non-Inverting Op Amps below and calculate the gain for each Op-Amp using one of the two equations below, and substituting in the values of the resistors. Record your answers in the indicated boxes below: [rn Rin OP AMP 1: Inverting or Non-Inverting (Circle One) 225 10K Gain: GND

Answer 1

Supply given to negative terminal i. e, Inverting Terminal So it is a INVERTING AMPLIFIER V_+ = 0 rightwardsdoublearrow v_- = 0 Apply KCL I_1 = I_2 V_in 0/R_in = 0 - V_out/R_f V_i/R_i = -V_out/R_f V_out/V_in = -R_f/R_i = -10 k/10k Gain = -1
