User-selectable Options (Refer to Figure 3)
Component pads are included to enable a variety of user
selectable circuits to be added to the amplifier differential
inputs, the VREF input, and the amplifier feedback loop. A
voltage divider and filter option can be added to establish a
power supply tracking common mode reference at the VREF
input, or a coaxial connection to the amplifier FB+ pin can be
made at the FB+ BNC connector. The differential inputs have
additional resistor placements for adding input attenuation,
or to establish input DC offsets through the VREF pin.
