VCA 5807 dB/V Gain Linearity

Hi, all

I want to know the dB/V Gain Linearity and Typical Gain Error Plot of Control Voltage vs Gain Error about vca5807.

But I can not find anything about that from data sheet of vca5807. The data sheet only says the Device-to-Device Gain Matching and Channel-to-Channel Gain Matching.
