The new integrated 2W audio amplifier from Maxim Integrated Products is designed notebook PCs, small flat-panel displays and portable DVD/media players. The MAX9756 amp features the company's automatic level control which increases average output power while reducing distortion and protecting the loud speakers. Together with the automatic level control, the MAX9756 combines a 150mA LDO and Maxim's DirectDrive headphone amplifier technology into a low-cost, low-component-count audio amplifier solution.

The MAX9756's 150mA LDO provides a clean power source for external components such as a DAC or CODEC. Meanwhile, the DC volume-control input provides full gain control. The DirectDrive technology produces a ground-referenced output from a single supply, eliminating the two bulky DC-blocking capacitors typically required between the amplifier and headphone. In addition, said the company, the industry-leading click-and-pop suppression eliminates audible transients on power and shutdown cycles.

The MAX9756 operates from a single 4.5V to 5.5V supply, produces up to 2W per channel, and features high 90dB PSRR and low 0.02 percent THD+N. This device is available in a small, 36-pin TQFN (6-by-6-by-0.8mm) package, and includes complete short-circuit and thermal-overload protection. Specifications are guaranteed over the extended -40C to 85C temperature range. Prices for the MAX9756ETX start at $1.10 (100,000-up, FOB USA).
