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 disable 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 power-down 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.

The ADA4853-1 is available in a 6-lead SC70, the ADA4853-2 is

available in a 16-lead LFCSP_VQ, and the ADA4853-3 is available

in both a 16-lead LFCSP_VQ and a 14-lead TSSOP. The

ADA4853-1 temperature range is −40°C to +85°C, while the

ADA4853-2/ADA4853-3 temperature range is −40°C to +105°C.
