establish a ground referenced input for dual supply
operation, or can be externally set to any reference level for
single supply operation. VREF should not be left floating.
User-selectable Options
Component pads are included to enable a variety of
user-selectable circuits to be added to the amplifier VREF,
inputs, outputs, and the amplifier feedback loops. The Inputs
(see Figure 3) have additional resistor and capacitor, and

jumper placements for loading and/or measurement of
frequency sensitive parameters.
The outputs (see Figure 4) have a 10kΩ load resistor to
ground and have additional resistor and capacitor
placements for loading.
NOTE: Operational amplifiers are sensitive to output
capacitance and may oscillate. In the event of oscillation,
reduce output capacitance by using shorter cables, or add a
resistor in series with the output.
