DVD/CD The AD8014 is a very stable and easy to use amplifier with fast Handheld Instruments overload recovery. The AD8014 has extremely low voltage and A-to-D Driver current noise, as well as low distortion, making it ideal for use Any Power-Sensitive High Speed System 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 PRODUCT DESCRIPTION drift. The input bias current into either input is less than 15 m A The AD8014 is a revolutionary current feedback operational at +25C with a typical drift of less than 50 nA/C over the amplifier that attains new levels of combined bandwidth, power, industrial temperature range. The offset voltage is 5 mV max output drive and distortion. Analog Devices, Inc. uses a propri- with a typical drift less than 10 m V/C. etary circuit architecture to enable the highest performance For a low power amplifier, the AD8014 has very good drive amplifier at the lowest power. Not only is it technically superior, capability with the ability to drive 2 V p-p video signals on but is low priced, for use in consumer electronics. This general 75 W or 50 W series terminated lines and still maintain more purpose amplifier is ideal for a wide variety of applications than 135 MHz, 3 dB bandwidth. including battery operated equipment.
