DV
within the MCP3909.
This pin requires appropriate bypass capacitors and
should be maintained to 5V ±10% for specified
operation.

3.2
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.
