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.
