Consider a practical op-amp where the power supply is VCC = +12V and VEE = -12V. The open loop gain is 106 and open loop bandwidth is 5Hz. What is the maximum positive input before which the output is saturated?(a) 12 mV(b) 0.012 mV(c) 24 mV(d) 12VI got this question at a job interview.This question is from Op-Amp Characteristics in chapter Op-amps and its Applications of Analog Circuits

Answer»

The CORRECT option is (b) 0.012 MV

Best explanation: The output is saturated at the input +VSat/AOL or –VSat/AOL.

For positive saturation, the maximum ALLOWABLE input is 12/10^6 = 0.012 mV.
