Note
1. 2. 3. The follow output voltage can be outputted by connecting this terminal to an output + or - terminal. Unless the output voltage is adjusted, this terminal should be open. In addition, the voltage can be adjusted not by shorting these terminals, but by connecting them to resistances as shown below. Arithmetic expression connected resistance: R ( K ) 3-1 Vo=(3.3*R+36.7)/(R+10) 3-2 Vo=(3.3*R+36.7)/(R+12.92) PIN CONNECTION 3-3 Vo=2.5*[2+2.7/(R+6.8)] 3-4 Vo=2.5*[2-2.7/(R+9.5)] 3-5 Vo=2.5+9.5(R+10.9)/(R+8.2) 3-6 Vo=2.5+22*(R+12.7)/(R+10)(Between two outputs) PIN SINGLE DUAL Bellcore TR-NWT-000332.
