Analog Audio

Our analog audio solutions include classic analog amplifiers, in class-AB or D, with output power ranging from <1 to 250 watts. A growing line of lower power audio solutions, are targeted for speaker and/or headphone outputs on mobile phones, PDAs, MP3 players and laptop PCs. They offer high fidelity, pop-free audio, with very low PSRR and power consumption for maximum quality and playback time. Other more powerful solutions cater to the equally space-and-power-conscious requirements of home audio systems, MP3 docking stations and flat-screen televisions.
