Overview
LT1395/LT1396/LT1397 Single/Dual/Quad 400MHz Current Feedback Amplifier FEATURES s s s s s s s s DESCRIPTIO 400MHz Bandwidth on ± 5V (AV = 1) 350MHz Bandwidth on ± 5V (AV = 2, –1) 0.
1dB Gain Flatness: 100MHz (AV = 1, 2 and –1) High Slew Rate: 800V/µs Wide Supply Range: ± 2V(4V) to ± 6V(12V) 80mA Output Current Low Supply Current: 4.
6mA/Amplifier LT1395: SO-8 Package LT1396: SO-8 and MSOP Packages LT1397: SO-14 and SSOP-16 Packages 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.
