Analog Ground pin connected to ground of circuit. It is a pin Single channel 8-bit ADC module. Or even to use as a standalone ADC module. As you can see in the image the voltage value is 1. Seven output Data bit pins from which output is obtained. However to make the internal clock to work we have to use a RC circuit.

TL — Programmable Reference Voltage. Clock Input pin; to give external clock. Submitted by admin on 10 October ADC is a very commonly used 8-bit analog to digital convertor. The time taken to convert the analog value to digital value is dependent on this clock source. The digital outputs vary from 0 to a maximum of An external clock can be given at the Clock IN pin.

RC timing resistor input pin for internal clock gen. Various sensors like temperature, pressure, force etc. Chip select is used if more than 1 ADC module is used. Differential Analog input. Interface SD Card with Arduino. Arduino based GPS receiver. ADC also has an inbuilt clock which can be used in absence of external clock. Output pin; Goes low when conversion is complete.

Hence, if you are looking for a compact ADC module with a decent resolution of 8-bit then this IC is for you. That is for every increase of Input pin; Low to high pulse is given to start the conversion. The step size can be adjusted by setting the reference voltage at pin9. Only if this is done the ADC value on the output side will be update. The chip select CS and Read R pin should also be grounded.

This high-density System-in-Package SiP integrates controller, power switches, and support components. National Semiconductor What is Web Browser.

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. These digital signals are used for further processing by the digital processors. ADC needs a clock to operate.

To set a particular voltage level as the reference value, this pin is connected to half the voltage. Activates ADC; Active low. SPI Module of Arduino. It is a single channel IC, i. Reference voltage for ADC conversion. External clock can be connected here, else RC can be used for accessing internal clock.
