AD8038/AD8039 is a low power 350MHz voltage feedback amplifier with an exceptionally low quiescent current of 1.0mA/amplifier typical (1.5mA max). It also features a wide supply range (3V to 12V) and is widely used in battery-powered instrumentation, filters, A/D drivers, level shifting, buffering, high density PC boards and photomultipliers.
The AD8038 (single) and AD8039 (dual) are high‑speed voltage‑feedback amplifiers designed for battery‑powered instrumentation, filters, A/D drivers and level‑shifting applications. They combine a low quiescent current of about 1 mA per amplifier with a high slew rate of 425 V/µs and low noise performance (8 nV/√Hz at 100 kHz).\n\nThe datasheet provides full electrical specifications, absolute maximum ratings, recommended operating conditions, package options (SOIC‑8, SC70‑5, SOT‑23‑8), ordering information and typical performance graphs such as frequency response, distortion, noise and power‑dissipation curves.
