Hi All,
I am using CY8ckit-059 like an oscilloscope by using its on-chip delta-sigma ADC. For maximum power transmission from the subject to the ADC I need to know the input impedance of the device.
Is there any way to find it?
Thanks in advance!

RaBa,
As Vasanth indicated the DeltaSigma ADC input impedance is VERY high. However the cost of such of a high impedance is that the DeltaSigma ADC is slower. The SAR ADC is faster but the input impedance is significantly lower unless you place a front-end track and hold op-amp between the input and the SAR ADC.
