ADC0809CCN description
The 8-bit A/D converter uses successive approximation as the conversion technique. The converter features a high impedance chopper stabilized comparator, a 256R voltage divider with an analog switch tree, and a successive approximation register. The 8-channel multiplexer can directly access any of the 8-single-ended analog signals.
The device eliminates the need for external zero to full-scale adjustments. Easy interfacing to microprocessors is provided by the latched and decoded multiplexer address inputs and latched TTL TRI-STATE output.
The design of the ADC0809 has been optimized by incorporating the most desirable aspects of several A/D conversion techniques. The ADC0809 offers high speed, high accuracy, minimal temperature dependence, excellent long-term accuracy and repeatability, and consumes minimal power. These features make this device ideally suited to applications from the process and machine control to consumer and automotive applications. For a 16-channel multiplexer with common output (sample/hold port) see ADC0816 datasheet.

Frequently Asked Questions
What is the internal structure of ADC0809?
ADC0809 is a CMOS monolithic successive approximation A / D converter, the internal structure shown in Figure 13.22, which consists of 8 analog switches, address latch and decoder, comparator, 8-bit switch tree A / D converter Device, successive approximation register, logic control and timing circuit.
What are the limitations of the adc0808 / 0809?
The ADC0808/0809 was designed for simple interface with analog inputs, especially transducers. There are a couple of limitations that follow: The source resistance must be below 10kohms for operation below 640kHz and below 5kohms for operation around 1.2MHhz. The source must remain stable while it is being sampled and should contain little noise.
What is ADC0809 data acquisition?
The ADC0808, ADC0809 data acquisition component is a monolithic CMOS device with an 8-bit analog-to-digital con- verter, 8-channel multiplexer and microprocessor compatible control logic. The 8-bit A/D converter uses successive ap- proximation as the conversion technique.
