DESCRIPTION
The
SP8542
(2 channel) and
SP8544
(4 channel) are 12-Bit serial in/out data acquisition systems
with a bi-directional serial interface. The devices contain a high speed 12-Bit analog to digital
converter, internal reference, and a 2 or 4 channel input mux which drives the internal sample/
hold circuitry. The
SP8542
is available in 16-pin PDIP and SOIC packages, and the
SP8544
is available in 18-pin PDIP and SOIC packages, specified over Commercial and Industrial
temperature ranges.
