38 MHz GBW — what it buys the signal chain
The OPA2350UA/2K5: A 38 MHz gain-bandwidth product means this op-amp can close a gain-of-10 stage with a 3.8 MHz small-signal bandwidth, or a unity-gain buffer with the full 38 MHz. That is enough headroom for 10× amplification of signals up to several MHz without significant gain roll-off, which is useful for video buffering, high-speed ADC drivers, and wideband filter stages. The 22 V/µs slew rate supports full output swings of several volts at frequencies above 1 MHz without slew-induced distortion — a practical limit for large-signal applications like waveform generation or line driving.
The rail-to-rail output stage maintains linearity close to the supply rails.
