Description

The LT®1886 is a 200mA minimum output current dual op amp with outstanding distortion performance. The amplifiers are gain-of-ten stable, but can be easily compensated for lower gains. The LT1886 features balanced, high impedance inputs with 4µA 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 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 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.
