ADC0816 Analog to Digital Converter (CMOS) 8-Bit 16-Input 40-CDIP

Description

The ADC0816, ADC0817 data acquisition component is a monolithic CMOS device with an 8-bit analog-to-digital converter, 16-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 an analog switch tree and a successive approximation register. The 16-channel multiplexer can directly access any one of 16-single-ended analog signals, and provides the logic for additional channel expansion. Signal conditioning of any analog input signal is eased by direct access to the multiplexer output, and to the input of the 8-bit A/D converter. 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 ADC0816, and ADC0817 has been optimized by incorporating the most desirable aspects of several A/D conversion techniques. The ADC0816, and ADC0817 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.
