MAX9727 Datasheet Quad Audio Line Driver

Manufacturer: Maxim Integrated (now Analog Devices)

General Description

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 component height.

A high 100dB PSRR and low 0.0005% THD+N ensures clean, low-distortion amplification of the audio signal.
