The LT
1886 is a 200mA minimum output current dual op
amp with outstanding distortion performance. The ampli-
fiers are gain-of-ten stable, but can be easily compensated
for lower gains. The LT1886 features balanced, high
impedance inputs with 4
μ
A maximum input bias current,
and 4mV maximum input offset voltage. Single supply
applications are easy to implement and have lower total
noise than current feedback amplifier implementations.
The output drives a 25
load to
±
4.3V with
±
6V supplies.
On
±
2.5V supplies the output swings
±
1.5V with a 100
load. The amplifier is stable with a 1000pF capacitive
load which makes it useful in buffer and cable driver
applications.
The LT1886 is manufactured on Linear Technology’s
advanced low voltage complementary bipolar process and
is available in a thermally enhanced SO-8 package.
