BH3857AFV

S The input impedance is 47kΩ.

S A buffer if R and C1 are not present.

S The gain can be set by R and the 20kΩ.

GVC = (R ) 20kΩ) / R

Note: Set C2 (input coupling) and C1 (used to set the

gain) depending on the frequency band used.

S A band-pass filter is constructed using a multiple-feedback type active filter.

f0 can be changed using the C valve.
