NJU9214
PRELIMINARY
43/4 DIGIT SINGLE CHIP DIGITAL MULTIMETER LSI
The
NJU9214
is a 43/4 digits single chip digital multimeter LSI with
42 segments bargraph display.
The
NJU9214
realizes high precision of ±40,000 counts measure-
ment 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 resis-
tance 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 Con-
verter, and Data output by the on chip RS-232C interface circuit.
The
NJU9214
is suitable for high precision and high performance
multimeter.
