Question:medium

In an inverting op-amp, the voltage gain is

Show Hint

For an ideal inverting amplifier, \[ \boxed{ A_v=-\frac{R_f}{R_{in}} } \] The minus sign indicates phase inversion.

  • \(+\dfrac{R_f}{R_{in}}\)
  • \(-\dfrac{R_{in}}{R_f}\)
  • \(-\dfrac{R_f}{R_{in}}\)
  • \(+\dfrac{R_{in}}{R_f}\)
Show Solution
