LT1818/LT1819

400MHz, 2500V/µs, 9mA

Single/Dual Operational

Ampliﬁers

FEATURES

DESCRIPTION

TheLT^®1818/LT1819aresingle/dualwidebandwidth,high

slew rate, low noise and distortion operational ampliﬁers

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.

The output drives a 100Ω load to ±±.8ꢀ with ±ꢁꢀ supꢂ

plies. On a single ꢁꢀ supply, the output swings from 1ꢀ

to 4ꢀ with a 100Ω load connected to 2.ꢁꢀ. The ampliﬁer

is unityꢂgain stable with a 20pF capacitive load without the

need for a series resistor. Harmonic distortion is –8ꢁdBc

APPLICATIONS

The LT1818/LT1819 are manufactured on Linear Techꢂ

nology’s advanced low voltage complementary bipolar

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

TSOTꢂ2± and SOꢂ8 packages; the LT1819 (dual op amp)

is available in MSOPꢂ8 and SOꢂ8 packages.
