D.Module.AD7722
6-channel, 16 bit data acquisition frontend
The D.Module.AD7722 offers 6 input channels with 16 bit resolution, all inputs
sampled simultaneously by high precision 200KSPS delta-sigma converters. The
inputs are fully differential with precision buffer amplifiers.
Delta-sigma conversion provides excellent linearity and dynamic charactersistics.
Antialiasing filters are inherent in the design.
Key application areas are power-line metering and acoustical and vibration
analysis using accelerometers, microphones, or hydrophones as signal sources.
The usable input frequency range is DC to 100kHz.
The D.Module.AD7722 connects to the DSP via a 16 bit parallel bus interface.
Up to four cards can be cascaded.
