It is a single channel IC, i. Input pin; 0804 adc data sheet the reference voltage for analog input. Data bit 0 to bit 7. Used with Clock IN pin when internal clock source is used. Skip to main content. Skip to main content. As you can see in the image the voltage value is 1. Input pin; Low to high pulse is given to start the conversion. Analog inverting Input; normally ground.
Hence, if you are looking for a compact ADC module with a decent resolution of 8-bit then this IC is for you. Interface SD Card with Arduino.
The step size can be adjusted by setting the reference voltage at 0804 adc data sheet.
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. The time taken to convert the analog value to digital value is dependent on this clock source. Write pin 0804 adc data sheet be pulsed high to start data conversion.
ADC Pinout, Description, Features & Datasheet
Differential Analog input. These digital signals are used for further processing by the digital processors.
Seven output Data bit pins from which output is obtained. Various sensors like temperature, pressure, force etc. Activates ADC; Active low. Interface GPS with Arduino. It is a pin Single channel 8-bit ADC module. Since the IC comes with an internal clock we do 0804 adc data sheet need many components to make it work.
Read pin must be grounded to read the Analog value. To set a particular voltage level as the reference value, this pin is connected to half the voltage. ADC needs a clock to operate. When this pin is not connected, the default reference voltage is the operating voltage, i. The step size at 5V is Digital Ground pin connected to ground of circuit.
Reference voltage for ADC conversion. The chip select CS 0804 adc data sheet Read R pin should also be grounded. The obtained value is 1. Goes high for interrupt request. Connect to ADC input. However to make the internal clock 0804 adc data sheet work we have to use a RC circuit.
Complete Technical Details can be found at the datasheet give at the end of this page.
The digital outputs vary from 0 to a maximum of 0804 adc data sheet An external clock can be given at the Clock IN pin.
Only if this is done the ADC value on the output side will be update. Clock Input pin; to give external clock.
ADC also has an inbuilt clock which can be used in absence of external clock. Analog Ground pin connected to ground of circuit.
Top menu About Us Advertise. Analog to digital converters find huge application as an intermediate device to convert the signals from analog to digital form. Or even to use as a standalone ADC module.
Chip select is used if more than 1 ADC module is used. RC timing resistor input pin for internal clock gen.
ADC Datasheet | ADC Pin Diagram & Description
External clock can be connected here, else RC can be used for accessing internal clock. ADC wdc a very commonly used 0804 adc data sheet analog to digital convertor. That is for every increase of SPI Module of Arduino. Output pin; Goes low when conversion is complete. Top menu About Us Contact.
