User-selectable Options (
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.

RREF
The output (Figure 4) has a 10kΩ load resistor to ground,
and has additional resistor and capacitor placements for
loading.
NOTE: Operational amplfiers are sensitive to output
capacitance and may oscilate. In the event of oscilation,
reduce output capacitance by using shorter cables, or add a
resistor in series with the output.
