LT1817IS

高速运算放大器 LT1817 - Quad 220MHz, 1500V/- s Operational Amplifiers with Programmable Supply Current

DESCRIPTION

The LT® 1815/LT1816/LT1817 are low power, high speed, very high slew rate operational amplifiers with excellent DC performance. The LT1815/LT1816/LT1817 feature higher bandwidth and slew rate, much lower input offset voltage and lower noise and distortion than other devices

with comparable supply current. A programmable current option LT1815 and LT1816A allows power savings and flexibility by operating at reduced supply current and speed. The circuit topology is a voltage feedback amplifier with the slewing characteristics of a current feedback

amplifier.
