MAX4147
300MHz, Low-Power, High-Output Current, Differential Line Driver
Maxim Confidential 
MyMaxim SubscriptionsProduct Details
The MAX4147 differential line driver offers high-speed performance while consuming only 100mW of power. Its amplifier has fully symmetrical inputs and outputs and uses laser-trimmed, matched, thin-film resistors to deliver 70dB CMR at 10MHz. Using current-feedback techniques, the MAX4147 achieves a 300MHz bandwidth and a 2000V/µs slew rate.
Optimized for differential, high-output-current applications such as transformer drivers, the MAX4147 drives ±2.6V into a 26.5Ω load (single-ended) or ±5.6V into a 53Ω load (differential). This device is preset for a closed-loop gain of 2V/V. Its ultra-low 0.008%/0.03° differential gain/phase allow for a variety of video and RF signal-processing applications.
For power-sensitive applications, the MAX4147 has a shutdown function that reduces supply current to less than 1mA. In addition, superior SFDR (-82dBc at 10kHz, RL = 33Ω) makes it ideal as a transformer driver for HDSL applications.
For a complete differential transmission link, use the MAX4147 with the MAX4144 line receiver (see the MAX4144 data sheet for more information).
