The AD7763 high performance, 24-bit, sigma delta analog to digital converter combines wide input bandwidth and high speed with the benefits of sigma delta conversion, as well as performance of 106dB SNR at 625 kSPS making it ideal for high speed data acquisition. A wide dynamic range combined with significantly reduced anti-aliasing requirements simplifies the design process. An integrated buffer to drive the reference, a differential amplifier for signal buffering and level shifting, an over-range flag, internal gain & offset registers and a low-pass digital FIR filter make the AD7763 a compact highly integrated data acquisition device requiring minimal peripheral component selection. In addition the device offers programmable decimation rates and the digital FIR filter can be adjusted if the default characteristics are not appropriate to the application. The AD7763 is ideal for applications demanding high SNR without necessitating design of complex front end signal processing. 获取更多权威电子资料 请登陆 www.eepw.com.cn ADI信号采集和振动分析的完整解决方案 AD7763 - Serial Interface, 625 kSPS, 24-Bit Sigma-Delta A/D Converter 产品描述 The AD7763 high performance, 24-bit, sigma delta analog to digital converter combines wide input bandwidth and high speed with the benefits of sigma delta conversion, as well as performance of 106dB SNR at 625 kSPS making it ideal for high speed data acquisition.
