9.2.6 Single-Ended Input to Differential Output Amplifier

The THS4531A can also be used to amplify and convert single-ended input signals to differential output signals. A basic block diagram of the circuit is shown in Figure 95 (VOCM and PD inputs not shown). The gain of the circuit is again set by RF divided by RG.
