    产品信息

    描述 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 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-STATEoutputs.The design of the ADC0816, ADC0817 has been optimized by incorporating the most desirable aspects of several A/D conversion techniques. The ADC0816,ADC0817 offers high speed, high accuracy, minimal temperature dependence, excellent long-term accuracy and repeatability, and consumes minima lpower. These features make this device ideally suited to applications from process and machine control to consumer and automotive applications. For similar performance in an 8-channel, 28-pin, 8-bit A/D converter, see the ADC0808, ADC0809 data sheet. (See AN-258 for more information.)特性Easy interface to all microprocessors Operates ratiometrically or with 5 VDC or analog span adjusted voltage reference 16-channel multiplexer with latched control logic Outputs meet TTL voltage level specifications 0V to 5V analog input voltage range with single 5V supply No zero or full-scale adjust required Standard hermetic or molded 40-pin MDIP package Temperature range −40°C to +85°Cor −55°C to +125°C Latched TRI-STATE output Direct access to “comparator in” and “multiplexer out” for signal conditioning ADC0816 equivalent to MM74C948 ADC0817 equivalent to MM74C948-1 All trademarks are the property of their respective owners.
