PRODUCT DESCRIPTION

The AD8014 is a revolutionary current feedback operational

amplifier that attains new levels of combined bandwidth, power,

output drive and distortion. Analog Devices, Inc. uses a propri-

etary circuit architecture to enable the highest performance

amplifier at the lowest power. Not only is it technically superior,

but is low priced, for use in consumer electronics. This general

purpose amplifier is ideal for a wide variety of applications

including battery operated equipment.

The AD8014 is a very high speed amplifier with 400 MHz,

–3 dB bandwidth, 4000 V/

µs slew rate, and 24 ns settling time.

The AD8014 is a very stable and easy to use amplifier with fast

overload recovery. The AD8014 has extremely low voltage and

current noise, as well as low distortion, making it ideal for use

in wide-band signal processing applications.

For a current feedback amplifier, the AD8014 has extremely

low offset voltage and input bias specifications as well as low

drift. The input bias current into either input is less than 15

µA

at +25

°C with a typical drift of less than 50 nA/°C over the

industrial temperature range. The offset voltage is 5 mV max

with a typical drift less than 10

µV/°C.

For a low power amplifier, the AD8014 has very good drive

capability with the ability to drive 2 V p-p video signals on

75

Ω or 50 Ω series terminated lines and still maintain more

than 135 MHz, 3 dB bandwidth.
