What are op-amp characteristics and its significance?


Answer: Op-amp characteristics are classified into two categories namely dc characteristics and ac characteristics. DC characteristics includes-

DRex Electronics
  • Input bias current.
  • Input offset current.
  • Input offset voltage.
  • Thermal drift.

Ac characteristics includes-

  • Frequency response.
  • Stability. Frequency compensation.
  • Slew rate.

The op-amp characteristics are important in practice because we can use them to compare the performance of various op-amp ICs and select the best suitable from them for the required application.
