MAX9727 Overview
The MAX9727 quad audio line driver with 3VRMS output is ideal for portable audio devices where board space and cost is at a premium. The device uses Maxim’s DirectDriveTM architecture that produces a ground-referenced output from a single supply, eliminating the need for large DC-blocking capacitors, saving cost, board space, and ponent height. A high 100dB PSRR and low 0.0005% THD+N ensures clean, low-distortion...
