GENERAL DESCRIPTION
The ADA4851-1 (single)/ADA4851-2 (dual)/ADA4851-4
(quad) are low cost, high speed, voltage feedback rail-to-rail
output op amps. Despite their low price, these parts provide
excellent overall performance and versatility. The 130 MHz,
−3 dB bandwidth and high slew rate make these amplifiers well-
suited for many general-purpose, high speed applications.
The ADA4851 family is designed to operate at supply voltages
as low as +3 V and up to ±5 V. These parts provide true single-
supply capability, allowing input signals to extend 200 mV
below the negative rail and to within 2.2 V of the positive rail.
On the output, the amplifiers can swing within 60 mV of either
supply rail.
With their combination of low price, excellent differential gain
(0.08%), differential phase (0.09º), and 0.1 dB flatness out to
11 MHz, these amplifiers are ideal for consumer video
applications.

... The input stage is the headroom limit for signals approaching the positive rail. Figure 40 shows a typical offset voltage vs. the input common-mode voltage for the ADA4851-1/ADA4851-2/ ADA4851-4 amplifiers on a ±5 V supply. Accurate dc performance is maintained from approximately 200 mV below the minus supply to within 2 the positive supply. For high speed signals, however, there are other considerations. Figure 41 shows − ...

... OVERLOAD BEHAVIOR AND RECOVERY Input The specified input common-mode voltage of the ADA4851-1/ ADA4851-2/ADA4851-4 is 200 mV below the negative supply to within 2 the positive supply. Exceeding the top limit results in lower bandwidth and increased rise time, as seen in Figure 41 and Figure 42. Pushing the input voltage of a unity- gain follower to less than 2 V from the positive supply leads to the behavior shown in Figure 43— ...

... 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 ...
