PACKAGE DESCRIPTIO
Output Offsets
The DC offset at the filter bandpass output is always equal
to V
(Notch and LP) depend on the mode of operation and
external resistor ratios. Table 5 illustrates this.
It is important to know the value of the DC output offsets,
especially when the filter handles input signals with large
