I am testing a EVAL-AD8333. As I understood, the evaluation board has a pre-amp (AD8332) before the demodulator stage (AD8333), which is followed by further amplification (AD8021). I ordered this as in the website is written "The board is shipped fully assembled and tested and is signal ready. A pair of AD8332 low-noise amplifiers (LNA) provide input matching and amplification for the differential input of the AD8333."
However, there is no amplification in the oscilloscope. I noticed that the AD8332 "Gain Control Voltage" is connected to ground, so I wonder if this is the reason why there is no amplification.
Thanks for any feedback on that,
