Description
CA3162, CA3162A August 1997 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.
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 L
Applications
* where low input pin 10 is not operated at pin 7 potential, a return path of not more than 100kΩ resistance must be provided for input bias currents. 4. The common mode input voltage above ground cannot exceed +0.2V if the full input signal range of 999mV is required at pin 11. That is, pin 11 may no
