Application Circuit Example 3 (Using 1 BPF)

Cautions 1.

With this application circuit, good interfering wave characteristics are obtained with a single

BPF. However, there is a drop in sensitivity.

2.

Ensure that the pin voltage does not exceed the power supply voltage.

Remark

Chip laminated ceramic capacitors (MURATA GRM36 or equivalent) should be used.
