AD7641 is the same input configuration of AD7679 differential ADC . If he wants SE(pseud-diff)ADC we can recommend the AD7988-5 or some similar SE ADC in the same family of AD7679 like the AD7666.
Is there any approach to increase my 18 bit(AD7679) resolution to 20bits.
The maximum throughput for the AD7679 is 570kSPS. Note that this is derived from the time between conversions, i.e one conversion cycle, rather than the max conversion time alone. The figures in the specs table will hold up until 570kSPS.
How I can under sample a signal of 4Mhz with signal bandwidth of 2Khz. ( used ADC is AD7679)
where would my fundamental and harmonic components lie.
After under sampling does over sampling can be used to increase the bit resolution.
PLease see attached list of the ADIs some of the latest differential ADCs with less tahn 2 LSB INL error. I have short listed this ADCs for DAQ systems application. I have included in the column on the file the throughput rate and full power…
