Overview

NJU9214 PRELIMINARY 4•3/4 DIGIT SINGLE CHIP DIGITAL MULTIMETER LSI ! GENERAL DESCRIPTION The NJU9214 is a 4•3/4 digits single chip digital multimeter LSI with 42 segments bargraph display.
The NJU9214 realizes high precision of ±40,000 counts measurement by the NJRC original dual-slope A to D converter and realizes also quick response bargragh display and auto-ranging by another high speed dual-slope A to D converter.
The input attenuator part is simplified because the resistor for resistance measurement is applied for voltage bleeder resistor.
Furthermore, the NJU9214 realizes root-mean-square measurement for AC voltage and current by connecting a External RMS-DC Converter, and Data output...
