AD8034ARZ-REEL

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 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. 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. They are rated to work over the industrial temperature range of -40°C to +85°C without a premium over commercial grade products.
