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.
The output drives a 100
load to
±
3.8V with
±
5V supplies.
On a single 5V supply, the output swings from 1V to 4V
with a 100
load connected to 2.5V. The amplifier is unity-
gain stable with a 20pF capacitive load without the need for
a series resistor. Harmonic distortion is –85dBc up to
5MHz for a 2V
P-P
output at a gain of 2.
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.
