What is an ADC pin?
An Analog to Digital Converter (ADC) is a very useful feature that converts an analog voltage on a pin to a digital number.
What is the function of the WR pin in ADC *?
What is the function of the WR pin? Explanation: WR is active low input used to inform the ADC0804 to start the conversion process.
Which pin of the ADC0804 indicates the end of conversion?
Interfacing ADC 0803/0804/0805 to 8086 using 8255: Here, port A of 8255 is used to read digital data from 8255. The start of conversion signal (WR and CS = low) generated using port B, PB0 pin. The end of conversion is detected by polling INTR pin through PC0.
How many pins does ADC have?
The ADC0804 is a commonly used ADC module, for projects were an external ADC is required. It is a 20-pin Single channel 8-bit ADC module. Meaning it can measure one ADC value from 0V to 5V and the precision when voltage reference (Vref –pin 9) is +5V is 19.53mV (Step size).
What is ADC and its types?
Main Types of ADC Converters Successive Approximation (SAR) ADC. Delta-sigma (ΔΣ) ADC. Dual Slope ADC. Pipelined ADC. Flash ADC.

What pin is used for ADC operational?
LPC2148 has an inbuilt 10-bit Successive Approximation ADC which is multiplexed among 6/8 input pins of ADC0/ADC1. The ADC reference voltage is measured across GND to VREF, meaning it can do the conversion within this range.
What is main role of ADC?
What is the main role of an ADC? Explanation: ADC corresponds to Analog to Digital Converter which is used to convert an analog signal into a digital. Digital signal can be processed and manipulated.
Why is ADC important?
Analog to Digital Conversion An analog to digital converter (ADC), converts any analog signal into quantifiable data, which makes it easier to process and store, as well as more accurate and reliable by minimizing errors.
