High-speed low distortion amplifier

8 May 2002 Analogue, Mixed Signal, LSI

Analog Devices' AD8007 high-speed current-feedback amplifier features extremely low distortion (-80 dB at 20 MHz) and low noise, while drawing 9 mA. Low power allows designers to minimise supply voltage/battery requirements and reduce cooling requirements. The high-speed amplifier has 600 MHz of bandwidth (G = +1) and a slew rate of 1000 V/µs. It features an impressive second harmonic distortion of -88 dB at 5 MHz and -80 dB at 20 MHz, while third harmonic distortion is -101 dB at 5 MHz and -84 dB at 20 MHz. Noise specs are 2,7 nV/rt Hz and 22,5 pA/rt Hz. The wide supply-voltage range of 5 V to 12 V and wide bandwidth makes the AD8007 highly suited for use in IF and baseband amplifiers, filters, ADC drivers and DAC buffers.
