A-to-D Driver
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.
Any Power-Sensitive High Speed System
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.
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.
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.
