A passive filter with Q=140 isn't easy to make, but feasible with good ferrite inductors. With modern OPs, there's no principle problem to design it as active filter, but as said, achieving a stable centre frequency is a practical issue. Well considered component selection and tuning are necessary.
The filter can be made as digital filter, but you didn't yet chose a suitable hardware. The mentioned ATmega isn't it. In case of a digital implementation, you have also to design AD and DA interfaces.
The filter specification might be elaborated. Are you intending a simple bandpass with one pole-pair, or a more complex one?
