Overview
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 Absolute Maximum Ratings: DC Supply Voltage (between Pin7 and Pin14), V+ .
