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

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

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.

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.
