    ICL7109

    and this is the 89C51's program which i have written and i am sure the programis absolutely right and the hardware is also right! the problem is that the ICL7109 is damaged  >:( cuz when i was setting refrence voltages from pin 39 and pin 36, by mistake the pins 39 and 40 were shorted out by...

    ICL7109

    Yeaaa i have also done this!... i applied no voltage at input & by giving LOW pulse at LBEN it tied all pins HIGH from B0 t0 B7.. This means, there is no effect of any input.. Ok right now the problem is this.. When i give Low pulse at LBEN which is low enable it tied all output pins...

    ICL7109

    I have seen many Application Sheet, just tell me wot does it mean? ICL7109, 12-bit dual-slope converter,  +/- 400.0mV 0.1mV resolution, ~12.5 conversions/s wot does  +/- 400 mV means and 0.1mV resolution, does it mean you can apply +/-400 mV input signal only? and the step size is 0.1mV or what...

    ICL7109

    I am using ICL7109 in a project, but it is not working when ever i give low pulse to LBEN or HBEN it do not convert analog data into digital but it converts all data output bits high i dont know whats going there with it, i think it is damaged can u tell me wot can happned wit it?
