The AD8033 is a single amplifier and the AD8034 is a dual amplifier. The AD8033/AD8034 FastFET op amps in Analog Devices, Inc., proprietary XFCB process offer significant performance improvements over other low cost FET amps, such as low noise (11 nV/√Hz and 0.7 fA/√Hz) and high speed (80 MHz bandwidth and 80 V/μs 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 work in more applications than similarly priced FET input amplifiers. In addition, the AD80
