Detailed 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 DirectDrive® architecture that produces a ground-referenced output from a single supply, eliminating the need for large DC-blocking capacitors and 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. Each MAX9727 amplifier can provide 3VRMS to a 1kΩ load with less than 0.003% THD+N while operating from a single +5V supply. Each MAX9727 amplifier can provide 2VRMS to a 1kΩ load with less than 0.003% THD+N while operating from a single +3.3V supply.
A shutdown input disables the amplifiers and reduces quiescent current consumption to less than 100nA. The MAX9727 features Maxim's comprehensive click-and-pop suppression circuitry that reduces audible clicks and pops during startup and shutdown.
The MAX9727 operates from a single 2.7V to 5.5V supply, consumes only 3mA of supply current per channel, and is specified over the -40°C to +85°C extended temperature range.
