APPLICATION INFORMATION
output gain-set design considerations (see Figure 9)
PWRO+ and PWRO– are low-impedance complementary outputs. The voltages at the nodes are:

(total differential response)
R1 and R2 are a gain-setting resistor network with the center tap to the GSR input.
A value greater than 10 k
and less than 100 k
for R1 + R2 is recommended because of the following:
The parallel combination of R1 + R2 and R
L
sets the total loading.
The total capacitance at the GSR input and the parallel combination of R1 and R2 define a time constant
that has to be minimized to avoid inaccuracies.
