Description
The ICL7104, combined with the ICL8052 or ICL8068,
forms a member of Intersil’ high performance A/D converter
family. The ICL7104-16, performs the analog switching and
digital function for a 16-bit binary A/D converter, with full
three-state output, UART handshake capability, and other
outputs for easy interfacing. The ICL7014-14 is a 14-bit
version. The analog section, as with all Intersil’ integrating
converters, provides fully precise Auto-Zero, Auto-Polarity
(including
±
0 null indication), single reference operation,
very high input impedance, true input integration over a
constant period for maximum EMI rejection, fully
rationmetric operation, over-range indication, and a
medium quality built-in reference. The chip pair also offers
optional input buffer gain for high sensitivity applications, a
built-in clock oscillator, and output signals for providing an
external Auto-Zero capability in preconditioning circuitry,
synchronizing external multiplexers, etc.
