[AKD5366VR-A]
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 = 47kΩ, C = 1µF)
(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 = 10kΩ, C = 4.7µF)
(2) Output Circuit
Pre-Amp outputs of AK5366VR are output to J3 (LOUT) and J6 (ROUT).
