Fig. 6-1. LPF External Circuit
6. LPF Block
The CXD3009Q contains an initial-stage secondary active LPF with numerous resistors and capacitors and an
operational amplifier with reference voltage.
The resistors and capacitors are attached externally, allowing the cut-off frequency fc to be determined flexibly.
The reference voltage (V
C
) is (AV

SS
)/2.
The LPF block application circuit is shown below.
In this circuit, the cut-off frequency is fc
≈
40kHz.
The external capacitors' values when fc = 30kHz and 50kHz are noted below as a reference.
The resistors' values do not change at this time.
When fc
≈
30kHz:
C1 = 200pF, C2 = 910pF
When fc
≈
50kHz:
C1 = 120pF, C2 = 560pF
