AD7851是一款14位高速模数转换器(ADC),采用5V单电源供电。当满足一组默认条件时,ADC上电,此时可作为只读ADC使用。该ADC含有自校准和系统校准选项,可确保操作精度不受时间和温度影响,还具有适合低功耗应用的多个省电选项。AD7851的吞吐量可达272 kHz。通过输入采样保持功能可在0.33 µs内采集一个信号,并采用伪差分采样方案。AD7851附加的优点是具有两个输入电压范围(0至VREF和以VREF/2为中心的-VREF/2至+VREF/2)。输入信号范围可至VDD,而且该器件能够转换140 kHz的全功率信号。CMOS结构可确保获得低功耗(典型值60 mW),且带省电模式(典型值5 µW)。这款器件提供三种封装:24引脚、0.3英寸宽、双列直插式封装(DIP);24引脚小形集成封装(SOIC);以及24引脚紧缩小型封装(SSOP)。
The AD7851 is a high speed, 14-bit ADC which operate from a single 5V power supply. The ADC powers-up with a set of default conditions at which time it can be operated as a read-only ADC. The ADC contains self-calibration and system calibration options to ensure accurate operation over time and temperature and has a number of power down options for low power applications.The AD7851 is capable of 272kHz throughput rate. The input track-and-hold acquires a signal in 0.33 µs and features a pseudo-differential sampling scheme. The AD7851 has the added advantage of two input voltage ranges ( 0 to VREF, and -VREF/2 to +VREF/2 centered about VREF/2). Input signal range is to VDD and the part is capable of converting full-power signals to 140 kHz.CMOS construction ensures low power dissipation (60 mW typ) with power-down mode (5 µW typ). The part is available in 24- pin, 0.3 inch-wide dual-in-line package (DIP), 24 lead small outline (SOIC) and 24 lead small shrink outline (SSOP) packages.
