PGA2 Performances
1) Measured with block connected to inputs through AMUX block. Normalized input sampling
frequency for input impedance is 512 kHz. This figure has to be multiplied by 2 for fs = 256 kHz
and 4 for fs = 128 kHz.
2) Input referred rms noise is 340 uV per input sample with gain = 1, 34 uV with gain = 10.This
corresponds to 47.5 nV/sqrt(Hz) for fs = 512 kHz and gain = 10.
PGA3 Performances
1) Measured with block connected to inputs through AMUX block. Normalized input sampling
frequency for input impedance is 512 kHz. This figure has to be multiplied by 2 for fs = 256 kHz
and 4 for fs = 128 kHz.
2) Input referred rms noise is 365 uV per imput sample with gain = 1, 36.5 uV with gain = 10.
This corresponds to 51.0 nV/sqrt(Hz) for fs = 512 kHz.
