Input pin; sets the reference voltage for analog input. However to make the internal clock to work we have to use a RC circuit. The chip select CS and Read R pin should also be grounded.

In the above circuit I have used a potentiometer to feed in a variable voltage of 0V to 5V to the Vin pin and the present Voltage is read using a voltmeter. ADC also has an inbuilt clock which can be used in absence of external clock. Write pin should be pulsed high to start data conversion.

As you can see in the image the voltage value is 1. An external clock can be given at aadc0804 Clock IN pin. ADC is a very commonly used 8-bit analog to digital convertor. Goes high for interrupt request.


The time taken to convert the analog value to digital value is dependent on this clock source. Since the IC comes with an internal clock we do not need many components to make it work. Digital Ground pin connected to ground of circuit.

SPI Module of Arduino. To set a particular voltage level as the reference value, this pin is connected to half the voltage. Seven output Data bit pins from which output is obtained.

The digital outputs vary dataseet 0 to a maximum of This high-density System-in-Package SiP integrates controller, power switches, and support components.

Choosing Motor For Robots. Input pin; Low to high pulse is given to start the conversion. What is Web Browser. The obtained value is 1. Arduino based GPS receiver.

National Semiconductor

It is a single channel IC, i. Hence, if you are looking for a compact ADC module with a decent resolution of 8-bit then this IC is for you. Analog inverting Input; normally ground. Interface SD Card with Arduino. Data bit 0 to bit 7. Connect to ADC input. Used with Clock IN pin when internal clock source is used.


RC timing resistor input pin for internal clock gen. It is a pin Single channel 8-bit ADC module. Interface GPS with Arduino.

These digital signals are used for further processing by the digital processors. When this pin is not connected, the default reference voltage is the operating voltage, i. Analog to digital converters find huge application as an intermediate device to convert the signals from analog to digital form.

Skip to main content. Reference voltage for ADC conversion. TL — Programmable Reference Voltage. Choosing Battery for Robots. Clock Input pin; to give external clock.

Only if this is done the ADC value on the output side will be update. Submitted by admin on 10 October That is for every increase of The step size can be adjusted by setting the reference voltage at pin9.
