LT1395/LT1396/LT1397 Single/Dual/Quad 400MHz Current Feedback Amplifi er
FEATURES DESCRIPTION
n
400MHz Bandwidth on ± 5V (AV = 1)
The LT ®1395/LT1396/LT1397 are single/dual/quad 400MHz n
350MHz Bandwidth on ±5V (AV = 2, –1)
current feedback amplifi ers with an 800V/μs slew rate and n
0.1dB Gain Flatness: 100MHz (AV = 1, 2 and –1)
the ability to drive up to 80mA of output current. n High Slew Rate: 800V/μs The LT1395/LT1396/LT1397 operate on all supplies from a n Wide Supply Range: ±2V(4V) to ±6V(12V) single 4V to ±6V. At ±5V, they draw 4.6mA of supply cur- n 80mA Output Current rent per amplifi er. The LT1395CS6 also adds a shutdown n Low Supply Current: 4.6mA/Amplifi er pin. When disabled, the LT1395CS6 draws virtually zero n LT1395: SO-8, TSOT23-5 and TSOT23-6 Packages supply current and its output becomes high impedance. LT1396: SO-8, MSOP and Tiny 3mm × 3mm × The LT1395CS6 will turn on in only 30ns and turn off in 0.75mm DFN-8 Packages 40ns, making it ideal in spread spectrum and portable LT1397: SO-14, SSOP-16 and Tiny 4mm × 3mm × equipment applications. 0.75mm DFN-14 Packages For space limited applications, the LT1395 is available in n Low Profi le (1mm) ThinSOT™ Package TSOT-23 packages, the LT1396 is available in a tiny 3mm × 3mm
APPLICATIONS
× 0.75mm dual fi ne pitch leadless DFN package, and the LT1397 is available in a tiny 4mm × 3mm × 0.75mm n Cable Drivers DFN package. n Video Amplifi ers The LT1395/LT1396/LT1397 are manufactured on Linear n MUX Amplifi ers Technology’s proprietary complementary bipolar process. n High Speed Portable Equipment They have standard single/dual/quad pinouts and they are n IF Amplifi ers optimized for use on supply voltages of ±5V.
