APPLICATIONS INFORMATION

U
– 3dB frequencies fL and fH are widely separated from this
peak.
The LTC1562’s fO is trimmed in production to give an
accurate 180
° phase shift in the configuration of Figure
6a with resistor values setting f0 = 100kHz and Q = 1.
Table 1 below shows typical differences between fO
values measured via the bandpass 180
° criterion and fO
values measured using the two other methods listed
above (Figure 6a, RIN = RQ).

LTC1562 Demo Board
The LTC1562 demo board is assembled with an LTC1562
or LTC1562A in a 20-pin SSOP package and power supply
decoupling capacitors. Jumpers on the board configure
the LTC1562 for dual or single supply operation and power
shutdown. Pads for surface mount resistors and capaci-
tors are provided to build application-specific filters. Also
provided are terminals for inputs, outputs and power
supplies.
This procedure can be iterated, adjusting the value of RT,
to find convenient values for CINA and CINB since resistor
values are generally available in finer increments than
capacitor values.
Different “fO” Measures
Standard 2nd order filter algebra, as in Figure 4 and the
various transfer-function expressions in this data sheet,
uses a center frequency parameter fO (or ωO, which is
2
πfO). fO can also be measured in practical ways, includ-
ing:
The frequency where a bandpass response has 180
°
phase shift
The frequency where a bandpass response has peak
gain
The geometric mean of the – 3.01dB gain frequencies in
a bandpass (
√LH in Figure 4)
An ideal mathematical 2nd order response yields exactly
the same frequency by these three measures. However,
real 2nd order filters with finite-bandwidth circuitry show
small differences between the practical fO measures,
which may be important in critical applications. The issue
is chiefly of concern in high-Q bandpass applications
where, as the data below illustrate, the different f0 mea-
surements tend to converge anyway for the LTC1562. At
low Q the bandpass peak is not sharply defined and the
