The MAX4142 differential line driver combines high-speed performance with fully symmetrical differential inputs and outputs. With an internally set +2V/V closed-loop gain, the MAX4142 is ideal for driving back-terminated cables and transmission lines.

This device utilizes laser-trimmed thin-film resistors and common-mode cancellation circuitry to deliver an outstanding 67dB at 10MHz common-mode rejection (CMR). Using current-feedback techniques, the MAX4142 achieves a 250MHz -3dB (A_V = +2V/V) bandwidth, a 70MHz 0.1dB bandwidth, and a 1400V/µs slew rate. Excellent differential gain/phase error and noise specifications make this amplifier an excellent choice for a wide variety of video and RF signal-processing applications.

The MAX4142 operates from ±5V power supplies and requires only 12.5mA of quiescent current. The output stage is capable of driving a 100Ω load to ±6V (differentially) or to ±3V (single-ended). The MAX4142 is available in a space-saving 14-pin SO package. For a pin-compatible, higher speed differential line driver, see the MAX4147 data sheet.
