Software-Selectable Input Ranges:  
±10V, ±5V, 0V to +10V, 0V to +5V (MAX196)  
The MAX196/MAX198 multirange, 12-bit data-acquisi-  
tion 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;

the MAX198. This range switching increases the effec-  
tive 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 con-  
verters are fault protected to ±16.5V; a fault condition  
on any channel will not affect the conversion result of  
the selected channel. Other features include a 5MHz  
bandwidth track/hold, 100ksps throughput rate, soft-  
ware-selectable internal/external clock, internal/external  
acquisition control, 12-bit parallel interface, and internal  
4.096V or external reference.

The MAX196/MAX198 employ a standard microproces-  
sor (µP) interface. A three-state data I/O port is config-  
ure d to op e ra te with 16-b it d a ta b us e s , a nd d a ta -  
access and bus-release timing specifications are com-  
patible with most popular µPs. All logic inputs and out-  
puts are TTL/CMOS compatible.

These devices are available in 28-pin DIP, wide SO,  
SSOP (55% smaller in area than wide SO), and ceramic  
SB packages. For 8+4 bus interface, see the MAX197  
and the MAX199 data sheets. An evaluation kit will be  
available after December 1995 (MAX196EVKIT-DIP).
