The LT
1969 is an adjustable current version of the
popular LT1886, a 200mA minimum output current, dual
op amp with outstanding distortion performance. The
adjustable current feature is highly desirable in applica-
tions where minimum power dissipation is required while
still being able to provide adequate line termination.
At nominal supply current, the amplifiers are gain of 10
stable and can easily be compensated for lower gains. The
LT1969 features balanced high impedance inputs with
4
A 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
making it useful in buffer and cable driver applications.
The LT1969 is manufactured on Linear Technology’s
advanced low voltage complementary bipolar process and
is available in a thermally enhanced MS10 package
