LT1815/LT1816/LT1817

Single/Dual/Quad 220MHz,

1500V/µs Operational Ampliﬁers

with Programmable Supply Current

DESCRIPTION

FEATURES

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

ﬂexibilitybyoperatingatreducedsupplycurrentandspeed.
