LT1886 - Dual 700MHz, 200mA Operational Amplifier

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.
