General Description
The MAX197 multi-range, 12-bit data-acquisition system (DAS) 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. This system provides 8 analog input channels that are independently software programmable for a variety of ranges: ±10V, ±5V, 0V to +10V, or 0V to +5V.

FEATUREs
♦ 12-Bit Resolution, 1/2LSB Linearity
♦ Single +5V Operation
♦ Software-Selectable Input Ranges:
   ±10V, ±5V, 0V to 10V, 0V to 5V
♦ Fault-Protected Input Multiplexer (±16.5V)
♦ 8 Analog Input Channels
♦ 6µs Conversion Time, 100ksps Sampling Rate
♦ Internal or External Acquisition Control
♦ Internal 4.096V or External Reference
♦ Two Power-Down Modes
♦ Internal or External Clock
