Hi,
I am calculating the Single -ended input range for LNA.
for example
LNA 24dB
VCAT 0dB
PGA 30dB
LPF 0dB
When calculated back from the ADC, the total attenuation is -54 dB at LNA, so simply
-54dB = 0.00199526
Since it is ADC Input 2Vpp differential, SE 1Vpp
Therefore LNA SE Input range = 0.00199526Vpp
Is it correct?
Is there any attenuation in the LPF?
Best regards,
Hiroshi
