APPLICATIONS
LTC1067/LTC1067-50
This would be used for operating Mode 3. Here, a 0
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.
