SINGLE-SUPPLY VIDEO AMPLIFIER
The ADA4851 family of amplifiers is well-suited for portable
video applications. When operating in low voltage single-supply
applications, the input signal is limited by the input stage
headroom. For additional information, see the Headroom
Considerations section. Table 6 illustrates the effects of supply
voltage, input signal, various gains, and output signal swing for
the typical video amplifier shown in Figure 45.
