MAX4205数据手册ADI中文资料规格书

描述 Description

The MAX4200–MAX4205 are ultra-high-speed, open-loopbuffers featuring high slew rate, high output current,low noise, and excellent capacitive-load-drivingcapability. The MAX4200/MAX4201/MAX4202 are singlebuffers, while the MAX4203/MAX4204/MAX4205 aredual buffers. The MAX4201/MAX4204 have integrated50Ω termination resistors, making them ideal for driving 50Ω transmission lines. The MAX4202/MAX4205 include 75Ω back-termination resistors for driving 75Ω transmission lines. The MAX4200/MAX4203 have no internal termination resistors.
The MAX4200–MAX4205 use a proprietary architectureto achieve up to 780MHz -3dB bandwidth, 280MHz0.1dB gain flatness, 4200V/µs slew rate, and ±90mAoutput current drive capability. They operate from ±5Vsupplies and draw only 2.2mA of quiescent current.These features, along with low-noise performance, makethese buffers suitable for driving high-speed analog-to-digitalconverter (ADC) inputs or for data-communicationsapplications.
