LT1818/LT1819

400MHz, 2500V/µs, 9mA

Single/Dual Operational Amplifiers

DESCRIPTIO

FEATURES

The LT^®1818/LT1819 are single/dual wide bandwidth,

high slew rate, low noise and distortion operational ampli-

fiers with excellent DC performance. The LT1818/LT1819

have been designed for wider bandwidth and slew rate,

much lower input offset voltage and lower noise and

distortion than devices with comparable supply current.

The circuit topology is a voltage feedback amplifier with

the excellent slewing characteristics of a current feedback

amplifier.

APPLICATIO S

■

The LT1818/LT1819 are manufactured on Linear

Technology’s advanced low voltage complementary bipo-

lar process. The LT1818 (single op amp) is available in

SOT-23 and SO-8 packages; the LT1819 (dual op amp) is

available in MSOP-8 and SO-8 packages.
