PRINCIPLES OF OPERATION
theory of operation (continued)
The following schematics depict the differences between the operation of the THS413x, fully differential
amplifier, in two different modes. Fully differential amplifiers can work with differential input or can be
implemented as single in/differential out.

Note: For proper operation, maintain symmetry by setting
Rf1 = Rf2 = Rf and R(g)1 = R(g)2 = R(g)
A = Rf/R(g)

RECOMMENDED RESISTOR VALUES
Figure 38. Single In With Differential Out
If each output is measured independently, each output is one-half of the input signal when gain is 1. The
following equations express the transfer function for each output:
VO

The second output is equal and opposite in sign:
VO
–1
