DESCRIPTIO
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 sup-
plies. 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 bipo-
lar process and are available in a variety of SOT-23, SO,
MSOP, SSOP and leadless DFN packages.
