 What is the typical unity gain bandwidth of a 741 op amp? 1Mhz What is the max current the a 741 op amp can source? 25mA What are the two "golden" laws when analyzing an op amp circuit with negative feedback? 1. bias current = 0 2. voltage at each input terminal is exactly equal Give the gain equation for a non-inverting op amp. A = 1 + Rf/R1 Give the gain equation for an inverting op amp. A = -(Rf/R1) What is the problem with using very small feedback resistors? Op Amps cannot source very much current. What is the problem with using very large feedback resistors? Non-idealities become more of an issue. What is the load current formula for a Howland VCIS amplifier? IL = Vin/R What is the gain formula for a differential amplifier? Vo = R2/R1(V2-V1) V2 = non-inverting terminal
