ams signal converters contain four or eight signal channels, and can be dynamically programmed in-process by means of multiple amplification levels. This makes them very well suited for multi-channel sensor systems in applications with dynamic amplification and a high sensor bandwidth. All the converters small: they are available in space-saving (Q)SOP packages or as Chip-on-Board(COB) packages.
