Description

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.

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

• Extended Temperature Range Version Available
