The AD8038 single amplifier in the SOIC-8 package has a dis- able feature. Despite being low power and low cost, the amplifier provides excellent overall performance. Additionally, it offers ahigh slew rate of 425 V/ µs and low input offset voltage of 3mVmax. ADI’s proprietary XFCB process allows low noise operation (8 nV/ √Hz and 600 fA/√Hz) at extremely low quiescent currents. Given a wide supply voltage range (3 V to 12 V), wide band- width, and small packaging, the AD8038 and AD8039 amplifiers are designed to work in a variety of applications where power and space are at a premium. The AD8038 and AD8039 amplifiers have a wide input common- mode range of 1 V from either rail and will swing within 1 V of each rail on the output. These amplifiers are optimized for driving capacitive loads up to 15 pF. If driving larger capacitive loads, a small series resistor is needed to avoid excessive peaking or overshoot. The AD8039 amplifier is the only dual, low power, high speed amplifier available in a tiny SOT-23-8 package, and the single AD8038 is available in both a SOIC-8 and an SC70-5 package. These amps are rated to work over the industrial temperature range of –40 °C to +85°C. –6 0.1 1000 110 100 –3 0 3 6 9 12 15 18 21 24 FREQUENCY – MHz G = +5 G = +2 G = +1 G = +10 Figure 1.
