The ADA4807-1 is a low power, low noise, rail-to-rail voltage feedback amplifier with exceptionally high performance. It is designed to have the lowest input noise among high speed, rail-to-rail amplifiers in the industry while operating on only 1mA or less of quiescent supply current, making it ideal for a wide range of applications from battery-powered, portable instrumentation to high speed systems where component density requires lower power dissipation. For systems with high dynamic range signals, the output voltage swings to within 50 mV of each rail, maximizing the output dynamic range, and the full, rail-to-rail input stage permits input operation up to and beyond the supply rails.
