    Part Number: VCA2612 Hello, in a hardware design i am using the VCA2612 with two differential input signals. The VCA2612 provides an active Feedback signal termination to achive lower system noise performance. Since it is not clear in the data sheet…

    Hello Takashi-san There are a few continuous time VCA's that take an analog control voltage, you could consider the (none of these are particularly good DC precision) VCA810 (lower speed, very poor harmonic distortion, but good for time domain) …

    Well just responding tothe AGC part, the dB/V gain control versions are what you want if you are building your own AGC - the VCA820 describes this but is likely too fast for what you need. You might also look at the VCA810 for a slower design point…
