A op-amp has an offset voltage of 1 mv and is ideal in all

Home » Analog Electronic Circuits » Analog electronics circuits miscellaneous » Question

A op-amp has an offset voltage of 1 mv and is ideal in all respects. If this op-amp is used in the circuit shown below the output voltage will be (select the nearest value)

1. 1 mV
2. 1 V
3. ± 1 V
4. 0 V

Correct Option: C

Output of the op-amp due to offset voltage of 1 mV

V_o = –		1 MΩ		V_i
		1 kΩ

or V_o = – (10³) (± 1 × 10^–3)
or V_o = ± 1 V
