SINGLE-TO-DIFFERENTIAL LINE DRIVER
The LMH6715's well matched AC channel-response allows a single-ended input to be transformed to highly
matched push-pull driver. From a 1V single-ended input the circuit of Figure 32 produces 1V differential signal
between the two outputs. For larger signals the input voltage divider (R₁ = 2R₂) is necessary to limit the input
voltage on channel 2.

DIFFERENTIAL LINE RECEIVER
Figure 33 and Figure 34 show two different implementations of an instrumentation amplifier which convert
differential signals to single-ended. Figure 34 allows CMRR adjustment through R₂.
