300MHz, Low-Power,
High-Output-Current, Differential Line Driver
_______________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 band-
width and a 2000V/µs slew rate.
Optimized for differential, high-output-current applica-
tions 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° dif-
ferential 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, R_L = 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).
