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, the output and the amplifier
feedback loop.
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

DESCRIPTION

To IN +
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.
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.
