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.
