MAXIM Integrated Products has released the MAX9704, a 15W stereo, class-D audio amplifier, available from Arrow Electronics .
The MAX9704 offers the audio quality typically associated with linear(Class-AB) amps and the benefitts of high-efficiency Class-D operation, eliminating the need for bulky, expensive heat sinking.
The MAX9704 employs Maxim's 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. This 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. 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 optimise the signal-to-noise 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 measuring 7mm x 7mm x 0.8mm. It operates over the extended temperature range from -40°C to +85°C.
