CA3162, CA3162A

A/D Converters for 3-Digit Display

August 1997

Features

Description

• Dual Slope A/D Conversion

• Multiplexed BCD Display

The CA3162E and CA3162AE are I L 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 imple-

• Capable of Reading 99mV Below Ground with Single ment a complete 3-digit display. The CA3162AE is identical

• Ultra Stable Internal Band Gap Voltage Reference

Supply

to the CA3162E except for an extended operating tempera-

ture range.

• Differential Input

The CA3161E is described in the Display Drivers section of

this data book.

• 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
