Introduction
Driving the balanced lines of high speed modems has become a very popular application for high speed, high output current, dual operational amplifiers. High amplifier speed is required to faithfully process signal passbands of at least 1MHz bandwidth, and high output currents are required to meet peak drive levels into 100Ω or 135Ω termination. Taking into account peak-to-average signal ratios in these applications, ...
