ES5136
3 1/2 DIGIT A/D CONVERTER W/LCD(Low power)
I、GENERAL DESCRIPTION
The ES5136 combines analog section and digital section on a
single monolithic CMOS integrated circuit to provide a high
performance, very low power 3 1/2 –digit A/D converter. Each device
includes a dual slope converter, internal reference, seven segment
decoders, display drivers, and clock. The ES5136 is designed to
interface with a liquid crystal display and includes a back plane drive.
The supply current is only 150µA, very suitable for 9V battery
operation.
To built a high performance digital panel meter, ES5136 needs
only few passive components and a LCD display. The true differential
input and reference of ES5136 are versatile and useful in all systems,
and these give the designers an uncommon advantage to make the
measurement of load cells, train gauges and other bridge type
transducers.
The ES5136 can be used as a plug-in replacement for the ES5106
in a wide variety of applications by changing only the passive
components of the ES5106. The ES5136 differs from the ES5106 in
that it includes lower power dissipation, improved temperature
coefficient of analog common and scale factor, and the design of
ZERO INTEGRATE phase to eliminate the overrange hangover and
hysteresis.

7. Analog COMMON
The voltage between V+ and COMMON is internally regulated at
about 3.1 volts. Thus the COMMON pin can set the common mode
voltage for battery operation or for any system where the input signals
are floating with respect to the power supply. As a reference, the
common voltage is adequate for many applications.
When the total supply voltage is large enough to cause the zener to
regulate(6.4V typical), the common voltage will have a low voltage
coefficient(0.001%/%), low output impedance (≅10Ω), and a
temperature coefficient typically less than 75ppm/℃.
The on-chip reference has some limitations. If there is a large
temperature variation, the reference temperature coefficient may not
take over and cause some errors. The other limitation is when the total
supply voltage is less than that which will cause the zener to regulate,
the common voltage will have a poor voltage coefficient. The
problems are of course eliminated if an external reference is used, as
shown in Figure 3.
