Description
Low battery detector.
Display hold and Max/Min.
Triplex LCD display.
The ES5108 is design for 3 1/2-Digit Digital Multi-
meter which combines an integrated A/D converter,
MAX/MIN, hold, short circuit beeper, low battery de-
tector, a frequency counter, and serial data output.
A ’HOLD’ input allows the ES5108 to hold the cur-
rent A/D readout or frequency readout. The frequency
counter is auto-ranging from 2KHz to 20MHz over a
five decade range with KHz and MHz annunciators.
Short circuit beeper will sound whenever the readout
is less than 30 after enabling the short circuit beeper.
This feature is useful in detecting short circuits without
watching the LCD.
Full 3 1/2-Digit Display.
Annunciators—Hold, Max/Min, KHz,
MHz, Low-bat, Continuance.
1 annunciator drive pin for unit display.
3 decimal point drivers with 3 independent
control pins.
Polarity driver.
Displays "OL" for input over range.
The ES5108 provides 3 independent decimal point driv-
ing pins for the manufacturer to determine which deci-
mal point or unit is display, the 3 decimal point drivers
are built-in ES5108.
Provides serial data output.
Guaranteed zero reading with zero input.
True polarity indication for precision null detec-
tion.
Application
Convenient 9V battery operation.
Low noise A/D converter:
Digital panel meters, digital multimeters, thermome-
ters, capacitance meters, pH meters, photometers, etc.
