These three bits have to be set as shown in the table below to access the respective analog channel. In the above circuit I have used a potentiometer to feed in a variable voltage of 0V datasheeg 5V to the IN1 pin and the present Voltage is read using a voltmeter.

This is an input pin which is made high to start conversion. When the conversion is complete the EOC pins goes low to indicate the end of conversion and data ready to be picked up. This is an output pin which goes high once the conversion is over. Analog Channel 1 to 5. ADC is an 8 bit analog to digital converter with eight adc00808 analog channels, i.


National Semiconductor

The default step size is dataheet The ADC needs some specific control signals for its operations like start conversion and bring data to output pins. TL — Programmable Reference Voltage. These three pins are used to select the channel. As you can see in the image the voltage value is 2. Submitted by admin on 13 October Vref is connected to ground normally.

IC ADC0808

End of Conversion EOC. Since the ADC IC can measure up to eight Analog voltage and also does daasheet have an internal clock slightly requires more components to make it work compared to its predecessor ADC Interface GPS with Arduino.

Choosing Motor For Robots. Choosing Battery for Robots.

National Semiconductor – datasheet pdf

Or even to use as a standalone ADC module. Output digital pins which gives the result of the ADC conversion.

Skip to main content. The obtained value is 2. Digital output bit 4. End of conversion; output pin; goes low when the conversion is over. Has to be made high to get output on output pins. Clock input; to provide external clock.


The right input analog voltage can be given to pins from IN1 to IN7, but the IC can read the voltage of only one channel at a time. It is a pin Eight channel 8-bit ADC module.

These 7 pins are the input pins for Analog voltage sensor. Output 2 -1 to 2 Start conversion; datashet pin; a low to high pulse is given.

ADC Pinout, How to Use & Datasheet

Has to be given clock signals 0V-5V 20Mhz approx. That is for every increase of Input pin; a low to high pulse brings data to output pins from the internal registers at end of conversion.

Once the channel is set it should be enabled by making the Address latch enabled ALE datssheet to go high momentarily. This pin is should be temporarily made high to select ADC channel.

Step size is the change in analog input to cause a unit change in the output of ADC. SPI Module of Arduino. This high-density System-in-Package SiP integrates controller, power switches, and support components.
