15W CLASS-D AMPLIFIER IS IDEAL FOR FLAT-PANEL TV AND PC-DISPLAY APPLICATIONS
SUNNYVALE, CA-February 19, 2004-Maxim Integrated Products
(NASDAQ: MXIM) introduces the MAX9704, a 15W stereo, Class-D audio amplifier. The MAX9704 offers the audio quality typically associated with linear (Class-AB) amps and the benefits of high-efficiency Class-D operation, eliminating the need for bulky, expensive heat sinking. The MAX9704 employs Maxim's patented spread-spectrum modulation scheme which reduces EMI emissions up to 6dB. The spread-spectrum modulation scheme allows the device to meet FCC EMI test levels without additional filtering, which makes them ideal for thin-profile applications such as flat-panel TVs and PC displays.
The MAX9704 offers 0.07% THD+N, high 80dB at 1KHz PSRR, and industry-leading click-and-pop performance levels. The device operates over a 10V to 25V single supply and can produce up to 15W per channel into a 8Ω load. Differential inputs and four selectable gain options allow the user to optimize the signal-to-noise (SNR) ratio under different load and input level conditions. Four flexible clocking options control the noise spectrum for a given application. The stereo MAX9704 is available in a 32-pin QFN (7mm x 7mm x 0.8mm) and operates over the extended temperature range (-40°C to +85°C). Prices for the MAX9704ETJ start at $3.00 (10,000-up, FOB USA).
