ADC804 DATASHEET PDF

The ADC ADC ADC ADC and. ADC are CMOS 8-bit successive approximation A D converters that use a differential potentiometric. ADCLCD, ADCLCD ADCLCD, ADCLCD SOT pin plastic dual in-line package (DIP). 0 to 70 °C. ADCCN. The ADC is a commonly used ADC module, for projects were an external ADC is required. It is a pin Single channel 8-bit ADC module.

Used with Clock IN pin when internal clock source is used.

The step size at 5V is The chip select CS and Read R pin should also be grounded. Digital Ground pin connected to ground of circuit. Interface SD Card with Arduino.

Output pin; Goes low when conversion is complete. Goes high dataasheet interrupt request. An external clock can be given at the Clock IN pin.

Hence, if you are looking for a compact ADC module with a decent resolution of 8-bit then this IC is for you. What is Web Browser. Activates ADC; Active low. Data bit 0 to bit 7. 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.

Connect to ADC input. Input pin; Low to high pulse is given to start the conversion. ADC needs a clock to operate. Write pin should be pulsed high to start data conversion.

ADC Datasheet | ADC Pin Diagram & Description

Chip select is used if more than 1 ADC module is used. Differential Analog input. Or even to use as a standalone ADC module. The step size can be adjusted by setting the reference voltage at pin9. Since the IC comes with an internal clock we do not need many ac804 to make it work. Arduino based GPS receiver. Analog to digital converters find huge application as an intermediate device to convert the signals from analog to digital form.

TL — Programmable Reference Voltage. The digital outputs vary from 0 to a maximum of That qdc804 for every increase of Choosing Battery for Robots. It is a pin Single channel 8-bit ADC module.

National Semiconductor

Analog 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. ADC also has an inbuilt clock which can be used in absence of external clock. When this pin is not connected, the default datashedt voltage is the operating voltage, i.

As you can see in the image the voltage value is 1.

Analog inverting Input; normally ground. It is a single channel IC, i. The obtained value is 1. Submitted by admin on 10 October The time taken to convert the analog value to digital value is dependent on this clock source. ADC is a very commonly used 8-bit analog to digital convertor. Virgin Galactic — Commercial Space Flight. Clock Input pin; to give external clock. External clock can be connected here, else RC can be used for accessing internal clock.

Input pin; sets the reference voltage for analog input.

Skip to main content. However to make the internal clock to work we have to use a RC circuit. Only if this is done the ADC value on the acd804 side will be update. Read pin must be grounded to read the Analog value. Choosing Motor For Robots.

These digital signals are used for further processing by the digital processors. RC timing resistor input pin for internal clock gen.
