Basic Electronic Components
ADC0808CCN PDIP-28 Analog to Digital Converter-ADC
The ADC0808CCN PDIP-28 Analog to Digital Converter-ADC is a µP compatible Analog-to-digital Converter (ADC) with 8-channel multiplexer. The 8-bit A/D converter uses a 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 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 has been optimized by incorporating the most desirable aspects of several A/D conversion techniques. The ADC0808 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 a process.SKU: n/a -
