Output digital pins which gives the result of the ADC conversion. The step size is decided based on set reference value.

ADC is an 8 bit analog to digital converter with eight input analog channels, i. As you can see in the image the voltage value is 2. Digital output bit 4. This pin is should be temporarily made high to select ADC channel. These three pins are used to select the channel.

Virgin Galactic — Commercial Space Flight.

Powers the IC typically with 5V. Skip to main content.

IC ADC0808

This is an input pin which is made high to start conversion. Since the ADC IC can measure up to eight Analog voltage and also does not have an internal clock slightly requires more components to make it work compared to its predecessor ADC Or even to use as a standalone ADC module.


End of Conversion EOC. The ADC needs some specific control signals for its operations like start conversion and bring data to output pins. 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. This high-density System-in-Package SiP integrates controller, power switches, and support components.

Submitted by arc0808 on 13 October The input which is to be converted to digital form can be selected by using three address lines.

National Semiconductor – datasheet pdf

These three bits have to be set as shown ad0808 the table below to access the respective analog channel. That is for every increase of Step size is the change in analog input to cause a unit change in the output of ADC.

Once the channel is set it should be enabled by making the Address latch enabled ALE pin to go high momentarily. When the conversion is complete the EOC pins goes low to indicate the end of conversion and data ready to be picked up. It is a pin Eight channel 8-bit ADC module. Arduino based GPS receiver. Connect to ground of the circuit.


Hence, if you are looking for a ADC module with a decent resolution of 8-bit that could measure up to 8 channels then this IC is for you. In the above circuit I have used a potentiometer to feed in a variable voltage of 0V to 5V to the IN1 pin and the present Voltage is read using a voltmeter. SPI Module of Arduino. Start conversion; input pin; a low to high pulse is given.

End of conversion; output pin; goes low when the conversion is over. Choosing Motor For Robots.

Analog Channel 1 to 5. Has to be made high to get output on output pins. Vref is connected to ground normally.
