Like many ICs, op amps have a wide variety of specifications to keep in mind. Keep these parameters in mind when looking through the realistic parameters below. Zero input offset voltage - the op amp’s output is zero when its inputs are equal.Zero input bias current - no current flows into the input terminals.Infinite slew rate - the op amp’s output can change as fast as it needs to.Infinite bandwidth - the op amp’s gain is not affected by frequency.Some of the characteristics of an ideal op amp are: The ideal model exists to make the math involved in design easier, but cannot exist in practice.
