[sdiy] Choosing an OTA for VCA

[Theo]

Problem with SSM seems to be that every new product has a "last time buy"
status the moment it becomes available.
OTOH I had good experience with the SSM 2024 quad VCA.
And the SSM2018 VCA also worked as advertised, low noise large, dynamic
range.

THAT is another company "that" makes nice VCA for audio applications.
Didn't use it but the THAT2180 looked really nice on paper.
For maximum headroom there is even a application bulletin which shows how to
operate the device @ +24V/-24V power.

If you don't mind stereo VCA with additional pan/balance and tone control
(just don't use if you don't need)
the easy to get TDA1524 and LM1036 are also worth looking into.
Not the over 110dB range and ultra hot input range of the THAT and SSM, but
still respectable.

HTH
