Converter/Filter Chipset for Voiceband Applications

14-Bit AD7871/AD7872 A/D and AD7840 D/A Converters; AD7371/AD7341 Switched-Capacitor Filters for Antialias/Reconstruction

The monolithic AD7871/AD7872 sampling analog-to-digital converters and AD7840 digital-to-analog converter provide fast 14-bit interfacing of microprocessors to analog signals. When accompanied by the AD7371 pre-digitizing antialiasing filter and the AD7341 reconstruction filter, which employ switched-capacitor circuitry, they form a complementary 4-chip set for digitizing analog signals in digital-signal-processing applications.
