Compare

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. The converter features a high-impedance chopper stabilized comparator, a 256R voltage divider with 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 and full-scale adjustments. Easy interfacing to microprocessors is provided by the latched and decoded multiplexer address inputs and latched TTL TRI-STATE outputs.

The design of the ADC0808 and ADC0809 has been optimized by incorporating the most desirable aspects of several A/D conversion techniques. The ADC0808 and ADC0809 offer high speed, high accuracy, minimal temperature dependence, excellent long-term accuracy and repeatability, and consume minimal power. These features make this device ideally suited to applications from process and machine control to consumer and automotive applications. For a 16-channel multiplexer with common output (sample/hold port) see ADC0816 data sheet. (See AN-247 (Literature Number SNOA595) for more information.)
