NTE2054
Integrated Circuit
A/D Converter for 3–Digit Display
Description:
The NTE2054 is an I²L monolithic Analog to Digital converter in a 16–Lead DIP type package that
provides a 3–digit multiplexed BCD output. This device, when used with an NTE2032 BCD–to–
Seven–Segment Decoder/Driver and a minimum of external parts, implements a complete 3–digit
display.
Features:
D Dual–Slope A/D Conversion
D Multiplexed BCD Display
D Ultra–Stable Internal Band–Gap Voltage Reference
D Capable of Reading 99mV below GND with a Single Supply
D Differential Input
D Internal Timing – No External Clock Required
D Choice of Low–Speed (4Hz) or High–Speed (96Hz) Conversion Rate
D “Hold” Inhibits Conversion but Maintains Delay
