for the vast majority of applications. If adjustment is
required the constant may be varied by adding a resistor in
parallel with the C
must be determined on a case by case basis.
Step 5: Selecting The Demod Filter Bandwidth
The inputs SEL0 and SEL1 control the demodulator filter
bandwidth in four binary steps (625Hz to 5000Hz in sweep,
1250Hz to 10000Hz in fixed-mode), see Table 3.
Bandwidth must be selected according to the application.
The demodulator bandwidth should be set according to

It should be noted that the values indicated in Table 1 are
nominal values. The filter bandwidth scales linearly with
frequency so the exact value will depend on the operating
frequency. Refer to the “Electrical Characteristics” for the
exact filter bandwidth at a chosen frequency.
