All who have tried to collect ADC K1113PV1 face usually with
two problems: where to buy it chip and where to get more money
for its purchase. K1113PV1 actually has a not so good
parameters, in contrast to, for example, from K1107PV1 and Here
is the o-ho-ho as.
Meanwhile, there exists a circuit A / D converter that uses a
more affordable items. This scheme I sent a VTS, which
apparently dug her somewhere in the wilds of FIDO. Article I
refined, leaving only the technical information.
And in the annex city43.z I decided to give a single
available in my program to digitize audio from
an ADC - Digital Factory v.1.0 by ZMAN.

To resume the conversation about the analog-digital
converters, throw shemku converter
155IR17 chip. Once went on a conversation. Until
still remains unclear the issue of port address
for ADC. So which port to connect the ADC?
The scheme capacity of 10 pF is selected so that from
ADC port was read a single value (if the register will work
nevovremya, it will be read intermediate data). Ft-clock
signal, for Leningrada1 I took the H1, the signal / RD - THIS
IS NOT A SIGNAL WITH The processor is the signal read from the
port of the ADC and should be shape signal decoding port ADC.
The input resistor is adjusted so that when applying the input
of 2.5 - 5 V from the port are read 255, ie First twisting on
the ground, and then quietly Turn off, as a result should be
read from the port number from 0 to 255, and upon reaching a
value of 255 stop to wind resistance. Configure the ADC
best with podbora capacitor applied to the input
(Resistor until the release) voltage of 2.5 V,
ie make sure that the port was read steadily to 255, and then
you can cheat a resistor.
