PGA2 Performances
1) Measured with block connected to inputs through AMUX block. Normalized input sampling frequen-
cy 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 corre-
sponds 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 frequen-
cy 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 cor-
responds to 51.0 nV/sqrt(Hz) for fs = 512 kHz.
