How do I use ADC0804?
How to use ADC0804 analog to digital converter?
- Make Cs (chip select) low(0) to activate the adc0804.
- Make WR (write) pin low (0).
- Make WR (write) pin high (1) after some delay small delay.
- Now check the INTR (interrupt) pin if it is high(1) conversion is running if it is low(0) the conversion is over.
What is the minimum voltage that ADC0804 can read?
ADC0804 Features The minimum should be 2.5 V. Fully functional with CMOS and TTL electronics devices. It has an internal clock with frequency 640KHz. Consist of Differential analog voltage input.
What is the minimum conversion time for ADC 0804?
ADC0804 Introduction. ADC0804 is a step-by-step comparison AD converter, using CMOS manufacturing process, 20 pins, 8-bit resolution, the input analog voltage range is 0-5V, and the typical conversion time is 100us.
Why do we use resistive voltage divider with ADC0804?
For 2.5V we use voltage divider as shown in circuit diagram, with same value resistor at both ends they share voltage equally, So each resistor holds a drop of 2.5V with a supply voltage of 5V. The chip works on RC (Resistor Capacitor) oscillator clock. As shown in circuit diagram, C1 and R2 form a clock.
What is the difference between ADC0804 and Max 112?
ADC0804 has 8 bits and MAX1112 has 1 bit for data output. ADC0804 is used for adc and dac conversions whereas MAX1112 is used for serial data transmissions.
What is the step size in ADC0804 if VREF 4 volt?
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).
How do you calculate R1 and R2 voltage divider?
A voltage divider circuit will normally look like this in a circuit with a series of 2 resistors.
- R1 = Resistor closest to input voltage (Vin)
- R2 = Resistor closest to ground.
- Vin= Input Voltage.
- Vout = Output voltage across R2 which is the divided voltage (1/4 of input voltage)
What is the difference between ADC0804 and maths 11 12?
What step have to be followed for interfacing a sensor to a microcontroller 8051?
5. What steps have to be followed for interfacing a sensor to a microcontroller 8051? Explanation: For interfacing a sensor with an 8051 microcontroller, we need ADC in between because output of sensor is analog and microcontroller works on digital signals only.
Which two pins for Ground are available in ADC0804?
Computer Science Engineering (CSE) Question. Their are two pins, that are available for ground in the ADC0804. one is for analog and the other is for digital pins.
