DESCRIPTION
The SC7106 and SC7107 are high performance, low power, 31/2 digit A/D converters. Included are seven segment decoders, display drivers, a reference, and a clock. The SC7106 is designed to interface with a liquid crystal  display  (LCD)  and  includes  a  multiplexed  backplane  drive;  the SC7107 will directly drive an instrument size light  emitting diode (LED) display.

FEATURES
