LT1397 - Quad 400MHz Current Feedback Amplifier

The LT1395/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 LT1395CS6 also adds a shutdown pin. When disabled, the LT1395CS6 draws virtually zero supply current and its output becomes high impedance. The LT1395CS6 will turn on in only 30ns and turn off in 40ns, making it ideal in spread spectrum and portable equipment applications.

For space limited applications, the LT1395 is available in TSOT-23 packages, the LT1396 is available in a tiny 3mm × 3mm × 0.75mm dual fine pitch leadless DFN package, and the LT1397 is available in a tiny 4mm × 3mm × 0.75mm DFN package.

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.
