ADuCM360 internal reference

Hello,

I got a couple of questions about ADuCM360:

  • How can I get voltage from internal reference off chip?
    • Can I use Int_Ref pin for it? From functional block diagram I can see, that Int_Ref pin is buffered internal reference output, but datasheet sais only to connect 0.47uF bypass cap to it.
    • If I use DAC in NPN-driver mode AIN8 connected to internal reference and can be used as ref output pin. In that case what is possible output current of AIN8?
  • Is there any information about on-chip high frequency oscillator PSRR?
