    Thinking of building a tunable state variable filter with a maximum f0 of about 130 KHZ, I started to consider what to use to replace the resistors that control f0, Q and gain.

    Amongst the options there is the AD633, analog multiplier and, absolutely new to me, the VCA SSM2164 SSM2164 | Low Cost Quad Voltage Controlled Amplifier | Variable Gain Amplifiers | Amplifiers and Comparators | Analog Devices

    Is that VCA suitable? Honestly, I am not sure of what to look for in its specs.

    Just in case, I decided already to avoid digital pots or DAC multipliers keeping the above (or similar) as my options.

    Help is appreciated.
