LT1395/LT1396/LT1397 Single/Dual/Quad 400MHz Current Feedback Ampli er FEATURES DESCRIPTION n 400MHz Bandwidth on 5V (A = 1) The LT 1395/LT1396/LT1397 are single/dual/quad 400MHz V n 350MHz Bandwidth on 5V (A = 2, 1) current feedback ampli ers with an 800V/s slew rate and V n 0.1dB Gain Flatness: 100MHz (A = 1, 2 and 1) the ability to drive up to 80mA of output current. V n High Slew Rate: 800V/s 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 ampli er. The LT1395CS6 also adds a shutdown n Low Supply Current: 4.6mA/Ampli 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 Pro le (1mm) ThinSOT Package TSOT-23 packages, the LT1396 is available in a tiny 3mm 3mm 0.75mm dual ne pitch leadless DFN package, and APPLICATIONS the LT1397 is available in a tiny 4mm 3mm 0.75mm n Cable Drivers DFN package. n Video Ampli ers The LT1395/LT1396/LT1397 are manufactured on Linear n MUX Ampli ers Technologys proprietary complementary bipolar process. n High Speed Portable Equipment They have standard single/dual/quad pinouts and they are n IF Ampli ers optimized for use on supply voltages of 5V.
