AD8014ACHIPS: 400 MHz, Low Power, High Performance Amplifier
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 proprietary circuit architecture to enable the highest performance amplifier at the lowest power. Not only is it technically superior, but it 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, -3dB 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.
