Actual bandwidth of this Avago isolation amplifier

I've few questions on the ACPL-790B/790A/7900:
http://www.avagotech.com/pages/en/optocouplers_plastic/plastic_miniature_isolation_amplifier/acpl-7900-000e/
According to the datasheet (Table 7, pp. 6), the typical gain of the parts is (G0,G1,G3) 8.2 V/V.
Figures 17 & 18 (pp. 10) show the frequency response of the part. Does it mean that with a gain of 8.2V/V, the actual bandwidth of the part is 200kHz/8 = 25kHz only?
Cheers

The gain plot is scaled for a reference of 8.2 V/V gain, not 1 V/V. therefore, 0 dB on the graph means an output voltage of 8.2V at 1V input for up to 70kHz or so.
