Claim 2:
3. The input sensing device according to claim 1, wherein each of the analog front-end circuits comprises:
a charge amplification component that differentially amplifies a first sensing signal and a second sensing signal that are respectively received by a first input terminal and a second input terminal, and outputs a first differential signal and a second differential signal through a first output terminal and a second output terminal, respectively;
a filter component that filters the first differential signal and outputs a first filtered signal and a second filtered signal in different frequency bands, and filters the second differential signal and outputs a third filtered signal and a fourth filtered signal in different frequency bands; and
a buffer component that outputs a first combined differential signal and a second combined differential signal based on the first to fourth filtered signals.
