ICL710x understanding

[varunme]

can anyone point me a good tutorial towards ICL710x series ICs ?

[varunme]

from datasheets , we cant get much , is there real world examples with explanations ?

 

[varunme]

can we directly apply a variable current or voltage from pot to the the ICL7106/7 and show corresponding voltage on a 7 segment ?

 

[mister_rf]

Yes, that's possible to do as the ICL7107 IC incorporates in a 40-pin case all the circuitry necessary to convert an analogue signal into digital and can drive a series of four seven-segment LED displays directly. The circuits built into the IC are: an analogue-to-digital converter (ADC), a comparator, a clock, a decoder and a seven-segment LED display driver.

 

[varunme]

can u show a very simple example with least components ?

 

[mister_rf]

See the datasheet for a very simple schematics.
And here you find attached the russian version of this circuit 'KR572PV2A'. :-D

@varunme: Everything can be found in data sheet. Many DVM's are literally basic circuit from data sheet + some input conditioning (Voltage, Current, Resistance, ...)
