GENERAL DESCRIPTION

The 8052/7101 A/D Pair, with its parallel BCD outputs, isideally suited for data processing applications or interfacingwith 3½-digit Liquid Crystal Displays. No external circuitryis required to demultiplex the information. In addition, ihas a start/reset input and busy output that allows easysynchronization to system requirements. The 8052/7101provides 4½-digit accuracy in a 3½-digit format with typicasystem performance like 5pA input leakage, auto-zero to

10µVwith less than 1µV/C drift and Linearity to 0.002%The 8052/7101 A/D pair also features conversion rate

from 10 seconds to 30 per second, making them ideall

suited for a wide variety of applications.
