_______________General Description
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;
±VREF, ±VREF/2, 0V to +VREF, and 0V to +VREF/2 for
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.
Two programmable power-down modes (STBYPD,
FULLPD) provide low-current shutdown between con-
versions. In STBYPD mode, the reference buffer
remains active, eliminating start-up delays.
The MAX196/MAX198 employ a standard microproces-
sor (P) interface. A three-state data I/O port is config-
ured to operate with 16-bit data buses, and data-
access and bus-release timing specifications are com-
patible with most popular Ps. 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).
