Product Summary

The ICL8068ACJD is a member of Intersil high performance A/D converter family. The ICL8068ACJD 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 ICL8068ACJD 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.
