Would you mind helping me to identify this IC? It has four pins on each side (total 16). I do not identify which firm this chip is.

The top marking says "H1N #847". It's used in a high-speed data collection card.

The chip is between the ADC and the data input. Maybe it is an AFE? enter image description here
