高速运算放大器 LT1396 - Dual 400MHz Current Feedback Amplifier
DESCRIPTION
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 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.
