ES5116 3 1/2 DVM with

hold and low battery indication

CYRUSTEK CO.

Features

Description

Guaranteed zero reading with zero input

Low input leakage current (1pA typical)

Internal Reference with low temperature drift

The ES5116 is low power monolithic CMOS 3 1/2 digit

LCD display A/D converter. It 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

(

C typically)

common a small temperature coefﬁcient of

Low noise (15uVp-p typical)

typically. The high accuracy characteristics of the

ES5116 perform very low linearity error and roll-over

Direct LCD display driver-no external compo-

nents required

error. The high input impedance (

) and low

input leakage current (1pA typical) give the ES5116 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 ratio-metric method. The dual slope conversion

technique makes the ES5116 a good normal and com-

mon mode rejection ratio. With a suitable oscillator fre-

quency, the ES5116 has a high rejection of 50Hz, 60Hz

and 400Hz line frequency noise. With single power

supply, a few passive components and a LCD display,

ES5116 can be built as high performance panel meter.

Existing Display hold, low battery ﬂag integration and

De-integration are four additional features.

Differential input and voltage reference

Precision null detection with true polarity at zero

Internal clock circuit

No additional active circuits required

Low Battery Indication

Display-Hold

Application

1. Digital panel meters

2. Digital multi-meters

3. Thermometers

4. Capacitance meters

5. pH meters

6. Photo-meters
