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.
