1. An integrated circuit (IC) op-amp has (a) two inputs and two outputs (c) two inputs and one output 2. Which of the following characteristics does not necessarily apply to an op-amp? (a) High gain (b) Low power (c) High input impedance (d) Low output impedance 3. A differential amplifier (a) is part of an op-amp (c) has two outputs (b) one input and one output (b) has one input and one output (d) answers (a) and (c) 4. When an op-amp is operated in the single-ended differential mode, (a) the output is grounded (b) one input is grounded and a signal is applied to the other (c) both inputs are connected together (d) the output is not inverted 5. In the double-ended differential mode, (a) a signal is applied between the two inputs (c) the outputs are different amplitudes 6. In the common mode, (a) both inputs are grounded (c) an identical signal appears on both inputs 7. Common-mode gain is (b) the gain is 1 (d) only one supply voltage is used (b) the outputs are connected together (d) the output signals are in-phase (a) very high (b) very low (c) always unity (d) unpredictable 8. If Apl = 3500 and Acm = 0.35, the CMRR is (a) 1225 (b) 10,000 (c) 80 dB (d) answers (b) and (c) 9. With zero volts on both inputs, an op-amp ideally should have an output equal to (a) the positive supply voltage (b) the negative supply voltage (c) zero (d) the CMRR 1.
