Fy6800, function generator, why this pin is unconnected?

[ptluis]

Hi friends,

I opened my function generator FY6800 and found that pin 19 (BW) of the DAC904 is not connected. I wonder if connecting this pin as indicated in the datasheet could improve some known issues?

According to the datasheet:

"Pin 19, Bandwidth/Noise Reduction Pin:
Bypass with 0.1μF to +VA for Optimum
Performance. (Optional)

For optional ac performance, an additional capacitor
(CCOMPEXT) should be applied between the BW pin and the
analog supply, +VA, as shown in Figure 7. Using a 0.1μF
capacitor, the small-signal bandwidth and output impedance of
the control amplifier is further diminished, reducing the noise
that is fed into the current source array. This also helps shunting
feedthrough signals more effectively, and improving the noise
performance of the DAC904."
