What is a key feature of the inverting amplifier?
That both the input signals and the feedback are applied at the inverting terminal of the op amp
For an ideal op amp the voltages and current are?
Voltages: V
1
= V
2
Current: I
1
= I
2
== 0
An inverting amplifier ________ the polarity of the input signal while __________ it.
Reverses
Amplifying
The voltage gain of a inverter is?

the gain depends only on the
external elements connected to the op amp
The inverting amplifier is used, for example, in a _______ converter
Current-to-Voltage
input voltage is applied directly to the noninverting input
and resistor is conected between the ground and inverting terminal.
