TEXAS INSTRUMENTS ADC0808CCN Convertitore Analogico Digitale,

Description

The ADC0808CCN is a µP compatible Analog-to-digital Converter (ADC) with 8-channel multiplexer. 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 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 process. Easy interface to all microprocessors Operates ratiometrically or with 5VDC or analog span adjusted voltage reference No zero or full-scale adjust required Green product and no Sb/Br
