ADC0808, ADC0809, the approximation technique is ex-tended to 8 bits using the 256R network. The A/D converter’s successive approximation register (SAR) is reset on the positive edge of the start conversion (SC) pulse. The conversion is begun on the falling edge of the start conversion pulseversion in process will be in-

Figure 1. ADC0808/ADC0809 Functional Block Diagram As mentioned earlier, there are 8 clock periods per approximation. Even though there is no conversion in progress the ADC0808/ADC0809 is still internally cycling through these 8 clock periods. A start pulse can
ADC0808 Pin Diagram | Features | Operation | Interfacing
Operation of ADC0808 Pin Diagram: ADC 0808/0809 has eight input channels, so to select desired input channel, it is necessary to send 3-bit address on A, B and C inputs. The address of the desired channel is sent to the multiplexer address inputs through port pins.
Analog to Digital Converter - ADC0808/ADC0809
The ADC0808/ADC0809 contains all of these and also has a multiplexer. This means that in order to get it to work, there is a total of seven control signals that must be sent from the FPGA. These are the address lines, A, B, and C, Address Latch Enable (ALE), Clock, Start, and Output Enable (OE).
ADC0804 Datasheet | ADC 0804 Pin Diagram & Description
DataSheet: ADC0804 is a very commonly used 8-bit analog to digital convertor. It is a single channel IC, i.e., it can take only one analog signal as input. The digital outputs vary from 0 to a maximum of 255. The step size can be adjusted by setting the reference voltage at pin9. When this pin is not connected,..
Microcontrollers 8051 Pin Description - tutorialspoint
The pin diagram of 8051 microcontroller looks as follows − Pins 1 to 8 − These pins are known as Port 1. This port doesn’t serve any other functions. It is internally pulled up, bi-directional I/O port. Pin 9 − It is a RESET pin, which is used to reset the microcontroller to its initial values. Pins 10 to 17 − These pins are known as Port 3. This port serves some functions like interrupts, timer input, control signals, serial
