Fig. 6-1. LPF External Circuit Example
6. LPF Block
The CXD2529Q incorporates a first-stage secondary active LPF and a reference voltage-applied operational
amplifier, which require many resistors and capacitors.
The cut-off frequency fc can be freely set due to the external resistors and capacitors.
Here, the reference voltage (Vc) is (AV
DD
– AV
SS
)/2.
Fig. 6-1 shows the LPF block application circuit.
In this circuit, the cut-off frequency is fc
≈
40kHz.
The external capacitors’ values when fc = 30kHz and 50kHz are indicated below for reference.
The resistors’ values do not change.
When fc
≈
30kHz:
C1 = 200pF, C2 = 910pF
When fc
≈
50kHz:
C1 = 120pF, C2 = 560pF
