MAX196BCAI+

The MAX196/MAX198 multirange, 12-bit data-acquisition systems (DAS) require only a single +5V supply for operation, yet convert analog signals at their inputs up to ±10V (MAX196) and ±4V (MAX198).
These systems provide six analog input channels that are indepen dently software programmable for a variety of ranges:±10V, ±5V, 0V to +10V, and 0V to +5V for the MAX196; ±VREF, ±VREF/2, 0V to +VREF, and 0V to +VREF/2 for the MAX198. This range switching increases the effective dynamic range to 14 bits and provides the flexibility to interface ±12V, ±15V, and 4mA to 20mA powered sensors to a single +5V system. In addition, these converters are fault protected to ±16.5V; a fault condition on any channel will notaffect the conversion result of the selected channel.Other features include a 5MHz bandwidth track/hold, 100ksps throughput rate, software-selectable internal/external clock, internal/external acquisition control, 12-bit parallel interface, and internal 4.096V or external reference.
