These three bits have to be set as shown in the table below to access the respective analog channel. Clock input; to provide external clock.
Powers the IC typically with 5V. The obtained value is 2. Choosing Battery for Robots. SPI Module of Arduino. TL — Programmable Reference Voltage.
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. This is an input pin which is made high to start conversion.
This pin is should be temporarily made high to select ADC channel. The default datashwet size is Analog Channel 1 to 5. End of Conversion EOC. Or even to use as a standalone ADC module.
Has to be made high to get output on output pins. Output digital pins which gives the result of the ADC conversion. Start conversion; input pin; a low to high pulse is given. Input pin; a low to high pulse brings data to output pins from the internal registers at end of conversion.
Step size is the change in analog input to cause a unit change in the output of ADC. It is a pin Eight channel 8-bit ADC module. Has to be given clock signals 0V-5V 20Mhz approx. Choosing Motor For Robots. When the conversion is complete the EOC pins goes low to indicate the end of conversion and data ready to be picked up.
The step size is datashete based on set reference value. Submitted by admin on 13 October As you can see in the image the voltage value is 2.
ADC is an 8 bit analog to digital converter with eight input analog channels, i. These three pins are used to select the channel. Output 2 -1 to 2 These 7 pins are the input pins for Analog voltage sensor. Virgin Galactic — Commercial Space Flight. Skip to main content. 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.

The input which is to be converted to digital form can be selected by using three address lines. 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. Digital output bit 4. Connect to ground of the circuit. Once the channel is set it should be enabled by making the Address latch enabled ALE pin to go high momentarily. Since the ADC IC can measure up to eight Analog voltage and also does not have an internal clock slightly requires more adf0808 to make it work compared to its predecessor ADC End of conversion; output pin; goes low when the conversion is over.
Interface GPS with Arduino. The ADC needs some specific control signals for its operations like start conversion and bring data to output pins.

This is an output pin which goes high once the conversion is over. Vref is connected to ground normally.
