General Description

The MAX199 multi-range, 12-bit data-acquisition system (DAS) requires only a single +5V supply for operation, and converts analog signals up to ±4V at its inputs. This system provides eight analog input channels that are independently software programmable for a variety of ranges: ±VREF, ±VREF/2, 0V to VREF, or 0V to VREF/2.
