功能描述

The LT1969 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 applications 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 4µA 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 Ohms load to ±4.3V with ±6V supplies. On ±2.5V supplies, the output swings ±1.5V with a 100 Ohms 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
