User-Selectable Options
(Figures 3 and 4)
Component pads are included to enable a variety of
user-selectable circuits to be added to the amplifier
inputs, the VREF input, outputs and the amplifier
feedback loops.
A voltage divider and filter option (Figure 3) can be
added to establish a power supply-tracking common

mode reference at the VREF input. The inverting and
non-inverting inputs have additional resistor placements
for adding input attenuation, or to establish input DC
offsets through the VREF pin.
The output (Figure 4) has additional resistor and
capacitor placements for loading.
