ES5106
3 1/2 DIGIT A/D CONVERTER W/LCD
１．
GENERAL DESCRIPTION
The ES 5106 is a low power monolithic CMOS 3 1/2 digit LCD
display A/D converter. The single chip ES 5106 provides all necessary
active devices which contains the internal clock, voltage reference, seven-
segment decoders, LCD display drivers and a back plane driver. The
improved internal zener reference voltage circuit gives the analog
common a small temperature coefficient of 60 ppm/℃ typically.
The high accuracy characteristics of the ES5106 perform very low
linearity error and rollover error. The high input impedance (>10
12
Ω)
and
low input leakage current (1pA typical) give the ES5106 a good
application in the field of high impedance circuit measurement. The
differential input and reference are suitable for measuring bridge
transducer or ohms by using ratiometric method.
The dual slope conversion technique makes the ES5106 a good
normal and common mode rejection ratio. With a suitable oscillator
frequency, the ES5106 has a high rejection of 50HZ, 60HZ and 400HZ
line frequency noise.
With single power supply, a few passive components and a LCD
display, ES5106 can be built as a high performance panel meter. Existing
TSC7106 or ICL7106 based systems may be upgraded without changing
external, passive component values.
