Product Summary

The MAX197ACNI is a multi-range, 12-bit data-acquisition system (DAS). The MAX197ACNI requires only a single +5V supply for operation, yet accepts signals at its analog inputs that may span both above the power-supply rail and below ground. The MAX197ACNI provides 8 analog input channels that are independently software programmable for a variety of ranges: ±10V, ±5V, 0V to +10V, or 0V to +5V. The applications of the MAX197ACNI include Industrial-Control Systems Robotics, Data-Acquisition Systems, Automatic Testing Systems, Medical Instruments and Telecommunications.
