Internal buffering can beselected to provide a very high input impedance for directconnection to transducers or low-level voltage signals. Burn-out current sources are provided that allow for the detectionof an open or shorted sensor. An 8-bit digital-to-analogconverter (DAC) provides an offset correction with a range of50% of the FSR (Full-Scale Range).The Programmable Gain Amplifier (PGA) provides selectablegains of 1 to 128 with an effective resolution of 19 bits at a gainof 128. The A/D conversion is accomplished with a second-orderdelta-sigma modulator and programmable FIR filter that pro-vides a simultaneous 50Hz and 60Hz notch. The reference inputis differential and can be used for ratiometric conversion.The serial interface is SPI compatible. Up to eight bits of dataI/O are also provided that can be used for input or output. TheADS1242 and ADS1243 are designed for high-resolutionmeasurement applications in smart transmitters, industrialprocess control, weight scales, chromatography, and portableinstrumentation.VDDVREF+VREF–XINXOUTAPPLICATIONSqqqqqqINDUSTRIAL PROCESS CONTROLLIQUID /GAS CHROMATOGRAPHYBLOOD ANALYSISSMART TRANSMITTERSPORTABLE INSTRUMENTATIONWEIGHT SCALESVDDClock Generator2uAOffsetDACAIN0/D0AIN1/D1AIN2/D2AIN3/D3AIN4/D4AIN5/D5AIN6/D6AIN7/D7MUXIN+IN–BUF+PGA2nd-OrderModulatorDigitalFilterControllerRegistersA = 1:128ADS1243Only2uAGNDGNDPDWNSerial InterfaceSCLKDINDOUTCSDRDYPlease be aware that an important notice concerning availability, standard warranty, and use in critical applications ofTexas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.All trademarks are the property of their respective owners.PRODUCTION DATA information is current as of publication date.Products conform to specifications per the terms of Texas Instrumentsstandard warranty.

Dictionary Of Fabric(A-C) 织品字典A-C
Burn-out Effects
A brocade-like pattern effect created on the fabric through the application of a chemical, instead of color, during the burn-out printing process. (Sulfuric acid, mixed into a colorless print paste, is the most common chemical used.) Many simulated eyelet effects can be created using this method. In these instances, the chemical destroys the fiber and creates a hole in the fabric in a specific design, where the chemical comes in contact with the fabric. The fabric is then over-printed with a simulated embroidery stitch to create the eyelet effect. However, burn-out effects can also be create...
