The AD7760 high performance 20-bit sigma delta analog to digital converter combines wide input bandwidth and high speed with the benefits of sigma delta conversion with performance of 100dB SNR at 2.5MSPS making it ideal for high speed data acquisition. Wide dynamic range combined with significantly reduced anti-aliasing requirements simplify 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 AD7760 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 AD7760 is ideal for applications demanding high SNR without necessitating design of complex front end signal processing.
