DESCRIPTION

The SP8121 is a complete data acquisition systems, featuring 8-channel multiplexer, internal

reference and 12-bit sampling A/D converter implemented as a single monolithic IC. The analog

multiplexer accepts 0V to +5V unipolar full scale inputs. Output data is formatted in 12-bit parallel.

The SP8121 is available in 32-pin plastic DIP or SOIC packages, operating over the commercial

temperature range.
