programmable state-variable filter
This programmable state-variable or universal filter configuration provides low-pass, high-pass, and bandpass
outputs, and is suitable for applications requiring microprocessor control of filter parameters.
As shown in Figure 10, DACA1 and DACB1 control the gain and Q of the filter while DACA2 and DACB2 control
the cutoff frequency. Both halves of the DACA2 and DACB2 must track accurately in order for the
cutoff-frequency equation to be true. With the TLC7528, this is easy to achieve.

p R1C1
The programmable range for the cutoff or center frequency is 0 to 15 kHz with a Q ranging from 0.3 to 4.5. This
defines the limits of the component values.
