DESCRIPTION
Single/Dual/Quad 400MHz
The LT
current feedback amplifi ers 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 cur-
rent per amplifi er. 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 fi ne 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.
