CA3162A Datasheet | Intersil

CA3162, CA3162A August 1997 A/D Converters for 3-Digit Display 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 plete 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. Features - Dual Slope A/D Conversion - Multiplexed BCD Display - Ultra Stable Internal Band Gap Voltage Reference - Capable of Reading 99m V 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 +999m V, “-” for Reading More Negative than -99m V When Used With CA3161E - Extended Temperature Range Version Available Ordering Information PART NUMBER CA3162E CA3162AE TEMP.
