GENERAL DESCRIPTION
The 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
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 AD8033/AD8034 have rail-to-rail
outputs for added versatility.
Despite their low cost, the amplifiers provide excellent overall
performance. They offer a high common-mode rejection of
−100 dB, low input offset voltage of 2 mV maximum, and low
noise of 11 nV/√Hz.

Figure 4. Small Signal Frequency Response
The AD8033/AD8034 amplifiers only draw 3.3 mA/amplifier of
quiescent current while having the capability of delivering up to
40 mA of load current.
The AD8033 is available in a small package 8-lead SOIC and a
small package 5-lead SC70. The AD8034 is also available in a
small package 8-lead SOIC and a small package 8-lead SOT-23.
They are rated to work over the industrial temperature range of
−40°C to +85°C without a premium over commercial grade
products.
