Compatible, 2-Chip, A/D Converter
Features
Description
• 16-Bit/14-Bit Binary Three-State Latched Outputs Plus
Polarity and Overrange
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
• Ideally Suited for Interface to UARTs and
Microprocessors
• Conversion on Demand or Continuously
• Guaranteed Zero Reading for 0V Input
• True Polarity at Zero Count for Precise Null Detection
• Single Reference Voltage for True Ratiometric
Operation
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.
• Onboard Clock and Reference
• Auto-Zero, Auto-Polarity
• Accuracy Guaranteed to 1 Count
• All Outputs TTL Compatible
• ±4V Analog Input Range
