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 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
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
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 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.
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 small packages: SOIC-8 and SC70.
The AD8034 is also available in small packages: SOIC-8 and
SOT-23-8. They are rated to work over the industrial temperature
range of –40°C to +85°C without a premium over commercial
grade products.
