Calculadora de Largura de Banda do Amplificador Operacional — Formula
## Op-Amp Gain-Bandwidth Product
### Formula
**BW = GBW / A_CL**
Where GBW is the gain-bandwidth product and A_CL is the closed-loop gain. Higher gain means lower bandwidth. This is a fundamental trade-off in op-amp circuits.
### Formula
**BW = GBW / A_CL**
Where GBW is the gain-bandwidth product and A_CL is the closed-loop gain. Higher gain means lower bandwidth. This is a fundamental trade-off in op-amp circuits.
Exemplo Resolvido
An op-amp with GBW = 1 MHz set to a gain of 10.
- BW = 1 MHz / 10 = 100 kHz
- BW in Hz = 1,000,000 / 10 = 100,000 Hz
- Gain in dB = 20 x log10(10) = 20 dB
