GENERAL DESCRIPTION
The ADA4853-1/ADA4853-2/ADA4853-3 are low power, low cost,
high speed, rail-to-rail output op amps with ultralow power disables
that are ideal for portable consumer electronics. Despite their low
price, the ADA4853-1/ADA4853-2/ADA4853-3 provide excellent
overall performance and versatility. The 100 MHz, −3 dB
bandwidth, and 120 V/µs slew rate make these amplifiers well-
suited for many general-purpose, high speed applications.
The ADA4853-1/ADA4853-2/ADA4853-3 voltage feedback op
amps are designed to operate at supply voltages as low as 2.65 V and up
to 5 V using only 1.4 mA of supply current per amplifier. To further
reduce power consumption, the amplifiers are equipped with a disable
mode that lowers the supply current to less than 1.5 µA maximum,
making them ideal in battery-powered applications.
The ADA4853-1/ADA4853-2/ADA4853-3 provide users with a
true single-supply capability, allowing input signals to extend
200 mV below the negative rail and to within 1.2 V of the positive
rail. On the output, the amplifiers can swing within 200 mV of
either supply rail.With their combination of low price, excellent
differential gain (0.2%), differential phase (0.10°), and 0.5 dB flatness
out to 22 MHz, these amplifiers are ideal for video applications.

... OVERLOAD BEHAVIOR AND RECOVERY Input The specified input common-mode voltage of the ADA4853-1/ ADA4853-2/ADA4853-3 is 200 mV below the negative supply to within 1 the positive supply. Exceeding the top limit results in lower bandwidth and increased rise time. Pushing the input voltage of a unity-gain follower to less than 1.2 V from the positive supply leads to an increasing amount of output error as well as increased settling time ...

... As is the case with all high speed applications, careful attention to printed circuit board (PCB) layout details prevents associated board parasitics from becoming problematic. The ADA4853-1/ ADA4853-2/ADA4853-3 can operate 100 MHz; there- fore, proper RF design techniques must be employed. The PCB should have a ground plane covering all unused portions of the component side of the board to provide a low impedance return path ...
