CA3162 A/D Converters for 3-Digit Display

• Dual Slope A/D Conversion
• Multiplexed BCD Display
• Ultra Stable Internal Band Gap Voltage Reference
• Capable of Reading 99mV Below Ground with Single Supply
• Differential Input
• Internal Timing - No External Clock Required
• Choice of Low Speed (4Hz) or High Speed (96Hz) Conversion Rate
• "Hold" Inhibits Conversion but Maintains Delay
• Overrange Indication
  • "EEE" for Reading Greater than +999mV, "-" for Reading More Negative than -99mV When Used With CA3161E

The CA3162E and CA3162AE are I²L monolithic A/D converters that provide a 3 digit multiplexed BCD output. They are used with the CA3161E BCD-to-Seven-Segment Decoder/Driver and a minimum of external parts to implement a complete 3-digit display. The CA3162AE is identical to the CA3162E except for an extended operating temperature range.
