CA3162: A/D Converters for 3-Digit Display

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.

The CA3161E is described in the Display Drivers section of this data book.

Key Features
  • 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
