CA3162
December 1993
A/D Converter for 3-Digit Display
Features
Description
• 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
The CA3162E and CA3162AE are I2L monolithic A/D con-
verters 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 imple-
ment a complete 3 digit display. The CA3162AE is identical
to the CA3162E except for an extended operating tempera-
ture range.
* The CA3161E is described in Display Drivers section of this data
book.
• Choice of Low Speed (4Hz) or High Speed (96Hz)
Conversion Rate
Ordering Information
• “Hold” Inhibits Conversion but Maintains Delay
• Overrange Indication
- “EEE” for Reading Greater than +999mV, “-” for
Reading More Negative than -99mV When Used
With CA3161E
