Analog V DD (AV DD )
DV DD is the power supply pin for the digital circuitry
within the MCP3905/06.
DV DD requires appropriate bypass capacitors and
should be maintained to 5V ±10% for specified

High-Pass Filter Input Logic Pin
(HPF)
HPF controls the state of the high-pass filter in both
input channels. A logic ‘ 1 ’ enables both filters,
removing any DC offset coming from the system or the
device. A logic ‘ 0 ’ disables both filters, allowing DC
voltages to be measured.
