Op-Amp Bandwidth Calculator
Calculate closed-loop bandwidth from gain-bandwidth product (GBW).
Parameters
Common values: 1MHz (LM741), 5.5MHz (TL072), 1GHz (AD8099)
Use absolute value (e.g., 10 for -10 inverting gain)
Key Formula
BW = GBW / |Gain|
Closed-loop bandwidth equals GBW divided by closed-loop gain

Gain-Bandwidth Trade-off
The gain-bandwidth product (GBW) is constant for a given op-amp. Higher gain means lower bandwidth.
Example: With 1 MHz GBW:
- Gain = 1: BW = 1 MHz
- Gain = 10: BW = 100 kHz
- Gain = 100: BW = 10 kHz
