Unformatted text preview: The power rails are at 15 V and the amplifier output is able to swing between a minimum V out,min = -12 V and a maximum of V out,max = +12 V. If V in is connected to ground, what is the range of voltages you could apply to V in + , so that V out lies between V out,min and V out,max ? (continued) Page 2 of 2 b) What is the voltage gain of the following op-amp circuit? [Voltage gain: A v = V out /V in ] Note: Following common practice, the power supply connections are not shown. What would A v be if we let R 1 go to (i.e., no resistor R 1 at all)? This type of circuit (no R 1 ) is commonly used. Why do you think it would be useful?...
