The simple-to-use spreadsheet requires the user to de-
fine the desired corner (or center) frequency, the pass-
band gain and a capacitor value for a choice of second or
third order Chebyshev or Butterworth lowpass or second
order bandpass filters.
The spreadsheet outputs the required external standard
component values and provides a circuit diagram.
Signal Ground
Both operational amplifiers within the LT1567 are de-
signed for inverting operation (constant common mode

input) and they share a single reference node on the chip.
Two pins permit access to this node: DC BIAS and
BYPASS. For a clean reference over a wide bandwidth, the
normal procedure is to connect DC BIAS to a DC potential
or ground and BYPASS to a decoupling capacitor that
returns to a ground plane.
Differential Output Feature
The multiple feedback filter section of Figure 1 inherently
includes two outputs of opposite signal polarity: a DC
inverting output from the OA (Pin 1) and a DC noninverting
