Bristol, UK, 5th Oct: Audium Semiconductor has launched an audio power amplifier IC which, at normal listening levels[1], is 20 times more efficient than competing devices, such as Class D[2] amplifiers, without compromising audio quality. The AS1001 operates from a nominal 1.5V power supply and delivers 100W peak power output. The amplifier is so efficient that battery-powered amplified loudspeakers can run for up to 10 months on a set of four C batteries, playing for three hours per day, vastly reducing CO2 from power generation and pollution from battery production[3].
