CA 3162 3-Digit A/D Converter with Multiplexed BCD Output

The CA 3162 is a monolithic analog-to-digital converter (A/D converter) designed for 3-digit displays. It features a multiplexed Binary-Coded Decimal (BCD) output and an ultra-stable internal band-gap voltage reference, making it ideal for digital panel meters, voltmeters, and other measurement instruments.

Key Features:

• Dual Slope A/D Conversion: Provides high accuracy and noise rejection.
• Multiplexed BCD Display: Simplifies interfacing with display drivers.
• Ultra-Stable Internal Band Gap Voltage Reference: Ensures consistent performance over time and temperature variations.
• Single Supply Operation: Capable of reading 99mV below ground with a single supply.
• Differential Input: Allows measurement of voltage differences between two inputs.
• Internal Timing: No external clock required, simplifying design.
• Selectable Conversion Rates: Choose between low speed (4Hz) or high speed (96Hz) conversion rates.
• Hold Function: Inhibits conversion while maintaining the current display value.
• Overrange Indication: Displays “EEE” for readings greater than +999mV and “-” for readings more negative than -99mV when used with the CA3161E.
