The AD8033 is available in a small package 8-lead SOIC and a With a wide supply voltage range from 5 V to 24 V and fully small package 5-lead SC70. The AD8034 is also available in a operational on a single supply, the AD8033/AD8034 amplifiers small package 8-lead SOIC and a small package 8-lead SOT-23. work in more applications than similarly priced FET input They are rated to work over the industrial temperature range of amplifiers. In addition, the AD8033/AD8034 have rail-to-rail −40°C to +85°C without a premium over commercial grade outputs for added versatility. products. 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.
