DESCRIPTION

Single/Dual/Quad 220MHz,

1500V/µs Operational Amplifiers

with Programmable Supply Current

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

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.
