AD8039ARZ-REEL7

The AD8038 (single) and AD8039 (dual) amplifiers are high speed (350 MHz) voltage feedback amplifiers with an exceptionally low quiescent current of 1.0 mA/ amplifier typical (1.5 mA maximum). The AD8038 single amplifier in the 8 - lead SOIC package has a disable feature. Despite being low power and low cost, the amplifier provides excellent overall performance. Additionally, it offers a high slew rate of 425 V/μs and a low input offset voltage of 3 mV maximum. The 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 bandwidth, 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 swing to 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 available in a 8 - lead SOT - 23 package, and the single AD8038 is available in both an 8 - lead SOIC and a 5 - lead SC70 package. These amplifiers are rated to work over the industrial temperature range of - 40°C to + 85°C.
