How to use the ADC 0808/0809

The specification of the ADC0809, total unadjusted error ± 1.2 LSB and ± 1 LSB with the resolution 8 bits, and have a conversion time 100ms and share resources that are used with a +5 volt, power 15mW, with the specifications of the ADC is what the ADC is easy to use interface in different series, just on a series of ADC is the need of adding a series of clock

Configuration of ADC 0808/0809

Configuration of the pin ADC0809 indicated that there were 28 units where the pins of each pin on the ADC function: Pin 8,14,15,17,18,19,20,21 digital data output is a result of conversion of the A DC where the eighth output can be directly connected to the data bus.
and pin 1,2,3,4,5,26,27,28 is the pin input, that there is a 8-pin or 8 input channels, this is the pin on the analog signal is converted will linked, while the pin is a pin 23,24,25 A, B, C that functions as a selector input lines which will be converted, and a pins as well as other ADC0804, so that input can be converted eight following truth table:

IN0	C	B	A
IN1	L	L	L
IN2	L	L	H
IN3	L	H	H
IN4	H	L	L
IN5	H	L	H
IN6	H	H	L
IN7	H	H	H

Truth Table ADC 0809

0809 ADC input must be analog voltage output from the sensor to its magnitude usually ranges from 0-5V.
