The LT ®1395/LT1396/LT1397 are single/dual/quad 400MHz current feedback amplifiers with an 800V/µs slew rate and the ability to drive up to 80mA of output current. The LT1395/LT1396/LT1397 operate on all supplies from a single 4V to ± 6V. At ± 5V, they draw 4.6mA of supply current per amplifier. The LT1395/LT1396/LT1397 are manufactured on Linear Technology’s proprietary complementary bipolar process. They have standard single/dual/quad pinouts and they are optimized for use on supply voltages of ± 5V.
