Maxim Integrated Products introduced a new DirectDrive, quad, audio line driver that provides a complete line-output solution for consumer audio systems. When operated from a single 5V supply, the MAX9727 outputs 3VRMS signal levels. With a 3.3V supply, the MAX9727 outputs 2VRMS signals.

According to the press release, the 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. Maxim explained that this eliminates the need for DC-blocking capacitors, which improves the low-frequency response, reduces distortion and saves cost.

In addition, the 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 0.0005 percent THD+N.

Designed for multichannel PC sound cards, STBs, A/V receivers, DVD players and portable media players, the MAX9727 is available in a small, Pb-free, 20-pin QSOP package. Specifications are guaranteed over the extended -400C to 850C temperature range. Prices for the MAX9727EEP+ start at 79 cents (1,000-up, FOB USA).
