Which pin of ADC 0808 indicates end of conversion?
Which pin of ADC 0808 indicates end of conversion?
Operation of ADC0808 Pin Diagram: After another 2.5 μs, the start of conversion (SOC) signal must be sent high and then low to start the conversion process. To indicate end of conversion ADC 0808/0809 activates EOC signal.

| 9 | OUT EN | Has to be made high to get output on output pins |
| 10 | CLOCK | Has to be given clock signals (0V-5V) 20Mhz approx. |
| 11 | Vcc | Powers the IC typically with 5V |
What is the purpose of ale pin of ADC 0808?
ALE. ALE is required to load the selected address lines into the ADC. Once loaded the multiplexer sends the appropriate channel to the converter on the chip.
Which type of ADC is IC 0808?
The ADC0808, ADC0809 data acquisition component is a monolithic CMOS device with an 8-bit analog-to-digital converter, 8-channel multiplexer and microprocessor compatible control logic. The 8-bit A/D converter uses successive approximation as the conversion technique.

Which pin is used to start the conversion of ADC from analog to digital?
The ADC converts an analog input voltage to a 10-bit digital value. The ADC is connected to an 8-channel Analog Multiplexer which allows each pin of PortA to be used as input for the ADC. The analog input channel is selected by writing to the MUX bits in ADMUX….
| MUX4..0 | Single-ended Input |
|---|---|
| 11111 | 0V (AGND) |
What is function of SOC signal in ADC 0809 0808 IC?
We put a channel number on these lines (0… 7) and latch it using ALE. SOC signal is given to indicate start of conversion. The channel voltage is internally sampled and held into a capacitor.
How many data pins are available for digital data in DAC 0808?
As you can depict from DAC0808 pinout diagram that it consists of 16 pins. Eight pins are digital input pins and IOUT is an analog output pin along with Vref+ and Vref- used to set a reference point for analog output.
What is the function of SOC signal in ADC 0809 0808 IC?
SOC signal is given to indicate start of conversion. The channel voltage is internally sampled and held into a capacitor. Conversion takes place internally using “Successive Approximations Algorithm”.
Which technique is used in ADC 0808?
successive approximation technique
The ADC 0808/0809 Chip ADC 0808/0809 is a monolithic CMOS device. This device uses successive approximation technique to convert analog signal to digital form.
What type of output is provided by DAC 0808?
analog signal output
The IC DAC0808 is a digital to analog converter, used to convert a digital data input to analog signal output, where the input is an 8-bit data.
What is the main role of an ADC Mcq?
1. 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.
What is the adc0808 IC?
Note: Complete Technical Details can be found at the ADC0808 datasheet given at the end of this page. The ADC0808 IC is a commonly used ADC module for projects were an external ADC is required. It is a 28-pin Eight channel 8-bit ADC module.
What is the digital input data of DAC IC 0808?
In other words, the digital input data to the DAC IC will be in the range of 00000000-11111111. When we apply 00000000 digital signal to input pins of DAC0808, it will generate zero analog voltage at the output pin (IOUT).
What is a 8 bit dac0808?
DAC0808 8-bit Digital to Analog Converter The DAC0808 IC is a monolithic digital to analog converter which takes an 8-bit digital data as an input and sends an analog signal at the output. It has high accuracy and utilizes very low power.
How many ADC values can be measured with a measuring device?
Meaning it can measure up to eight ADC value from 0V to 5V and the precision when voltage reference (Vref –pin 9) is +5V is 19.53mV ( Step size ). That is for every increase of 19.53mV on input side there will be an increase of 1 bit at the output side.
