GENERAL DESCRIPTION
The ADA4851-1 (single)/ADA4851-4 (quad) are low cost, high
speed, voltage feedback rail-to-rail output op amps. Despite
their low price, the ADA4851-1/ADA4851-4 provide excellent
overall performance and versatility. The 130 MHz, −3 dB
bandwidth and 375 V/µs slew rate make these amplifiers well-
suited for many general-purpose, high speed applications.
The ADA4851-1/ADA4851-4 are designed to operate at supply
voltages as low as 3 V and up to ±5 V, using only 2.5 mA of supply
current. To further reduce power consumption, the amplifier is
equipped with a power-down mode, which lowers the supply
current to 0.2 mA.
The ADA4851-1/ADA4851-4 provide users with a 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 amplifier can swing within 70 mV of either supply rail.
With their combination of low price, excellent differential gain
(0.04%), differential phase (0.06º), and 0.1 dB flatness out to
12 MHz, these amplifiers are ideal for consumer video applications.

... OVERLOAD BEHAVIOR AND RECOVERY Input The specified input common-mode voltage of the ADA4851-1/ ADA4851-4 is 200 mV below the negative supply to within the positive supply. Exceeding the top limit results in lower bandwidth and increased settling time, as seen in Figure 39 and Figure 40. Pushing the input voltage of a unity-gain follower less than 2 V from the positive supply leads to the behavior shown in Figure 41— ...
