The LT
廬
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.
The output drives a 100鈩?load to
鹵3.8V
with
鹵5V
sup-
plies. On a single 5V supply, the output swings from 1V
to 4V with a 100鈩?load connected to 2.5V. Harmonic
distortion is 鈥?0dB for a 5MHz, 2V

output driving a

The LT1815/LT1816/LT1817 are manufactured on Linear
Technology鈥檚 advanced low voltage complementary bipo-
lar process and are available in a variety of SOT-23, SO,
MSOP, SSOP and leadless DFN packages.
