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.

|
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.
