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.
The output (Figure 4) has a series 50Ω back-termination
resistor to drive 50Ω cables, and additional resistor and
capacitor placements for loading.
