MAXIM Integrated Products, represented in Australia by Arrow Electronics Australia Pty Ltd , has introduced a DirectDrive, quad audio line driver that provides a complete line-output solution for consumer audio systems, the MAX9727.

When operated from a single +5V supply, the MAX9727 outputs 3VRMS signal levels; with a +3.3V supply, the MAX9727 outputs 2VRMS signals.

The MAX9727 is ideal for multi-channel PC sound cards, set-top boxes, A/V receivers, DVD players and a variety of portable media players.

Maxim's innovative DirectDrive technology creates an on-chip negative supply, which allows the MAX9727 line driver to output full line-level signals while operating from a single power supply.

As an added benefit, the device's output signal is biased at ground. This eliminates the need for dc-blocking capacitors, which improves the low-frequency response, reduces distortion and saves cost.

Integrated differential inputs improve system noise management. Gain can be precisely controlled by external resistors.

The MAX9727 features a high 100dB PSRR, 111dB signal-to-noise ratio and ultra-low 0.0005% THD+N. Industry leading click-and-pop suppression eliminates audible transients on power and shutdown cycles.

The MAX9727 is available in a small, lead-free, 20-pin QSOP package.

Specifications are guaranteed over the extended -40°C to +85°C temperature range.
