What is the function of OE pin in 0808 ADC?

What is the function of OE pin in 0808 ADC?

What is the function of OE pin in 0808 ADC?

The ADC0808 Pin Diagram and ADC 0809 are monolithic CMOS devices with an 8-channel multiplexer. These devices are also designed to operate from common microprocessor control buses, with tri-state output latches driving the data bus.

Which of the following is output pin of ADC 0808?

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 are the important features ADC 0808?

The ADC0808, ADC0809 offers high speed, high accuracy, minimal temperature dependence, excellent long-term accuracy and repeatability, and con- sumes minimal power. These features make this device ideally suited to applications from process and machine control to consumer and automotive applications.

What is the difference between ADC 0804 and ADC 0808?

ADC 0804 has one analog input, whereas in 0808 we can give 8 analog inputs. Using select lines in 0808, one can multiplex the input analog channels. In 0808 ADC converter, one have two reference voltage (Vref+ and Vref-). In 0804, there is WR pin whereas in the 0808 there is pin called SC.

What type of signal ADC 0808 is required on SOC pin?

The most extreme level of the input voltage must be reduced proportionally to +5V. The ADC 0808 IC requires a clock signal of typically 550 kHz, ADC0808 is used to convert the data into digital form required for the microcontroller.

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….

MUX4..0 Single-ended Input
00001 ADC1
00010 ADC2
00011 ADC3
00100 ADC4

Which pin of ADC indicates end of conversion?

Explanation: INTR pin tells about the end of the conversion (output) and WR pin tells us to start the conversion (input). 10.

Which is 8 bit ADC IC?

The TLV571 is an 8-bit data acquisition system that combines a high-speed 8-bit ADC and a parallel interface. The device contains two on-chip control registers allowing control of software conversion start and power down via the bidirectional parallel port.

Which pin of ADC 0808 indicates end of conversion?

ADC 0808

Pin No Function Name
6 Start conversion; input pin; a low to high pulse is given SC
7 End of conversion; output pin; goes low when the conversion is over EOC
8 Digital output bit 4 D3
9 Input pin; a low to high pulse brings data to output pins from the internal registers at end of conversion Output enable

How big is the adc0808 IC pinout?

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. 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 ).

How big is an 8 bit ADC module?

It is a 28-pin Eight channel 8-bit ADC module. 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.

What is the channel number of ADC 0809?

ADC 0809 is an 8 channel, 8 bit ADC. It can convert an analog voltage input into an 8 bit digital data output. To select an input out of 8 options, there are three select lines (C, B and A). We put a channel number on these lines (0…7) and latch it using ALE.

Where can I find the ADC0804 datasheet?

Note: Complete Technical Details can be found at the ADC0804 datasheet given at the end of this page. 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.
