MSM6650 Family
Each device of the MSM6650 family contains a 4-order LPF using the switched capacitor filter
technology. The attenuation is –40 dB/oct.
The cutoff frequency and LPF frequency change depending on the sampling frequency (f
SAM
). The
cutoff frequency is 0.4 time as low as the sampling frequency.
The LPF frequency characteristics at f
SAM
= 8 kHz are shown below.
