The cut-off frequency of the input circuit on this evaluation board is as below. When changing the cut-off frequency,
change the constant of the each resistor and capacitor.
(1) The cut-off frequency of HPF in front of the Pre-Amp : fc = 3.4Hz (R = 47k

(2) The cut-off frequency of HPF, which is composed by the input resistance of the IPGAL/R pins and the capacitor
of between the Pre-Amp output and the IPGA input : fc = 3.4Hz. (R = 10k
