19-1106; Rev 1; 11/96 KIT ATION EVALU E L B A AVAIL 300MHz, Low-Power, High-Output-Current, Differential Line Driver 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). ________________________Applications ____________________________Features ♦ 2V/V Fixed Gain ♦ 300MHz -3dB Bandwidth ♦ 2000V/µs Slew Rate ♦ 82dBc SFDR at 10kHz ♦ 70dB CMR at 10MHz ♦ Low Differential Gain/Phase: 0.008%/0.03° ♦ High Output Drive: ±5.6V into 53Ω ♦ Low Power: 100mW ______________Ordering Information PART TEMP.

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.
