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.
The output drives a 100Ω load to ±3.8V with ±5V supplies.
On a single 5V supply, the output swings from 1V to 4V
with a 100Ω load connected to 2.5V. Harmonic distortion
is –70dB for a 5MHz, 2V_P-P output driving a 100Ω load
in a gain of –1.
The LT1815/LT1816/LT1817 are manufactured on Linear
Technology’s advanced low voltage complementary bipolar
process and are available in a variety of TSOT-23, SO,
MSOP, SSOP and leadless DFN packages.
