Op amps circuit
Both have resistor called Rf connecting the output to the inverting pin and have a resistor called R1 connected to inverting pin
Inverting op amp
power connected to inverting pin and has a resistor called R1 in the way. Non inverting pin connected to gnd
Non inverting
Power connected to non inverting. Inverting connected to gnd with resistor in the way
Op amp characteristics
Open loop gain
The gain with no resistors attached want it to be ∞
Input impedance
Resistance of the input want it to be ∞ so no current is drawn
Output impedance
Resistance of the output want it to be 0 so it can provide as much current as needed
Infinite slew rate
Want it to be ∞ so the output changes as quick as possible. Higher the slew rate the quicker the output changes since slew=V/t
Common mode rejection ratio (CMRR)
How well the op amp rejects signals that is common in both inputs and only amplifies the difference between both signals. Want it to be ∞
