#102739 - TLC7628 DAC |
I'm currently integrating a two channel DAC into an AT89S8252 embedded system. I can't, however, figure out the purpose of two pins on the chip. Can anyone tell me what RFBA and RFBB are supposed to do on this chip:
http://focus.ti.com/lit/ds/symlink/tlc7628.pdf From the suggested circuits, they appear to be feedback resistors for gain adjustment, but is that their only purpose? What happens if I leave them unconnected? |
