ADC0809CCN (Analog to Digital Converters)
The ADC0808, ADC0809 data acquisition component is a monolithic CMOS device with an 8-bit analog-to-digital microprocessor compatible control logic. The 8-bit A/D converter uses successive approximnation 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 8-single-ended analog signals. converter, 8-channel multiplexer pand The device eliminates the need for external zero and full-scale adjustments Easy interfacing microprocessors is provided by the latched and decoded multiplexer address inputs and latched TTL TRI-STATE outputs. The design of the ADC0808, ADC0809 has been optimized by incorporating the most desirable aspects of several A/D conversion techniques. The ADC0808, ADC0809 offers high speed, high accuracy, minimal dependence, accuracy and repeatability, and consumes minimai power. These features make this device ideally suited to applications from process and machine control to and automotive applications. channel multiplexer with common output (sampie/hojd port) see ADC0816 data sheet.
