Maxim MAX4147ESD Datasheet
_______________General Description
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).

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
