Question

How to choose an IC for a high electrical noise environment?

(a) Low degree of noise immunity

(b) High degree of noise immunity

(c) Low degree of noise reduction

(d) High degree of noise reduction

The question was asked by my school principal while I was bunking the class.

My query is from Noise topic in division Practical Limitations of Op Amp Circuits of Linear Integrated Circuits

Answer 1

Right choice is (b) High degree of noise immunity

Let me elaborate: In a high electrical noise environment an IC with a high degree of noise immunity will minimize the amount of special care needed for proper circuit operation.
