The cell is the 3rd order Butterworth low pass filter with cut-off frequency adjustment in a wide range.
The cell is the 3rd order Butterworth low pass filter with cut-off frequency adjustment in a wide range. There are 2 modes for cut-off frequency programming: manual and automatically. The generator is used to control filter cut-off frequency in an automatic mode. Generator oscillation frequency correlates with cut-off frequency which can be fixed by digital code ctrl<6:0>.
There are 4 operation modes with different rated signal level under the same value of distortion. Greater level of signal corresponds to a higher current consumption.
It is possible to use several LPF with one generator for multichannel systems.
