One of the most common applications of the op-amp is the inverting amplifier. The output is inverted relative to the input and the amplification gain is determined by the ratio of the feedback resistor (R2) to the input resistor (R1). 1. Analytically determine the "gain" of the inverting amplifier shown in Figure 2 (not including Capacitor C1). C1 1 nF R2 10 kQ Vss R1 Vdd Vin 1 ko Vout OA1 V2 V3 TLO81 5 V -5 V V1 ^) sine 1 kHz Vss

1. Two resistors are connected in series. What is the effective component tolerance of the series connection? 2. The voltage gain of the op-amp in the network shown below is -R₂/R₁ Specify the resistor tolerances so that the uncertainty in this gain in the worst case will be less than 3%. R₂ 1 + Vin ww
