毕业论文中英文资料外文翻译文献 外文资料 DS1722 Digital Thermometer With scientific and technological progress and development of the types of temperature sensors increasingly wide range of application of the increasingly widespread, and the beginning analog toward digital, single-bus, dual-bus and bus-3 direction. And the number of temperature sensors because they apply to all microprocessor interface consisting of automatic temperature control system simulation can be overcome sensor and microprocessor interface need signal conditioning circuit and A / D converters advantages of the drawbacks, has been widely used in industrial control, electronic transducers, medical equipment and other temperature control system. Among them, which are more representative of a digital temperature sensor DS18B20, MAX6575, the DS1722, MAX6636 other. This paper introduces the DS1722 digital temperature sensor characteristics, the use of the method and its timing. Internal structure and other relevant content. FEATURES: Temperature measurements require no external components; Measures temperatures from -55°C to +120°C. Fahrenheit equivalent is -67°F to +248°F; Thermometer accuracy is ±2.0°C; Thermometer resolution is configurable from 8 to 12 bits (1.0°C to 0.0625°C　resolution); Data is read from/written to via a Motorola Serial Peripheral Interface (SPI) or standard 3-wire serial interface; Wide analog power supply range (2.65V - 5.5V); Separate digital supply allows for 1.8V logic; Available in an 8-pin SOIC (150 mil), 8-pin USOP, and flip chip package; PIN ASSIGNMENT FIGURE 1 PIN ASSIGNMENT PIN DESCRIPTION: SERMODE - Serial Interface Mode. CE - Chip Enable. SCLK - Serial Clock. GND – Ground. VDDA - Analog Supply Voltage. SDO - Serial Data Out. SDI - Serial Data In. VDDD - Digital Supply Voltage. DESCRIPTION: The DS1722 Digital Thermometer and Thermostat with SPI/3-Wire Interface provides temperature readings which indicate the temperature of the device. No additional co
