ठराविक op-amp चा लाभ हा वारंवारतेच्या व्यस्त प्रमाणात असतो. एक op-amp त्याच्या लाभ-बँडविड्थ उत्पादनाद्वारे वैशिष्ट्यीकृत आहे.
उदाहरणार्थ, 1 MHz च्या लाभ-बँडविड्थ उत्पादनासह op-amp 200 kHz वर 5 चा फायदा आणि 1 MHz वर 1 चा फायदा होईल. हे कमी-पास वैशिष्ट्य जाणूनबुजून सादर केले आहे कारण ते प्रबळ ध्रुव सादर करून सर्किट स्थिर करते. याला आवृत्ति क्षतिपूर्ति म्हणून ओळखले जाते.
गणना:
लाभ × बँडविड्थ = 1 MHz
कोणत्याही वारंवारतेवर, लाभ बँडविड्थ उत्पादन समान असेल = 1 MHz
लाभ = 1
∴ बँडविड्थ = \(\frac{1~MHz}{1}\)
बँडविड्थ = 1000 kHz
