APPLICATIONS INFORMATION
WUU
U
This would be used for operating Mode 3. Here, a 0Ω
resistor in the R61 position also works. Jumpers JP52 and
JP62 perform the same functions on the B side of the part.
The buffering amplifier can be configured for inverting or
noninverting operation. For inverting applications, con-
nect jumper JP2 positions 1 and 2. Additionally, connect
jumper JP4 for split supply applications or JP8 for a single
supply. For a noninverting application, connect jumper
JP2 positions 2 and 3.
Several other jumpers should be connected as follows:
JP1: Install a jumper wire from position 1 to position 2,
leave the other positions open.
JP5: Install a jumper wire if split supply, leave open if
single supply.
JP6: Leave open.
JP7: Install a jumper wire.
JP9: Install a jumper wire if single supply, leave open if
split supply.
