DescriptionThe AD8033/AD8034 FastFET amplifiers are voltage feedback amplifiers with FET inputs, offering ease of use and excellent performance. The AD8033 is a single amplifier and the AD8034 is a dual amplifier. The AD8033/AD8034 FastFET op amps in ADI's proprietary XFCB process offer significant performance improvements over other low cost FET amps, such as low noise(11 nV/Hz and 0.6 fA/Hz) and high speed(80 MHz GAIN bandwidth and 80 V/s slew rate).
With a wide supply voltage range from 5 V to 24 V and fully operational on a single supply, the AD8033/AD8034 amplifiers will work in more applications than similarly priced FET input amps. In addition, the AD8033/AD8034 have rail-to-rail outputs for added versatility.
Despite their low cost, the amplifiers AD8033 provide excellent overall performance. They offer high common-mode rejection of 100 dB, low input offset voltage of 2 mV max, and low noise of 11 nV/Hz.
