LONDON Sidense Corp. (Ottawa, Canada), a develop of antifuse-based non-volatile memory, has announced that its one-time programmable (OTP) technology was included in Audium's recently announced high efficiency AS1001 audio power amplifier chip. The Sidense OTP macro is used to predefine register defaults after a chip reset.
At normal listening levels, the AS1001 is 20 times more efficient than a traditional Class D power amplifier. Operating from a nominal 1.5V power supply and delivering 100W peak power output, the AS1001 is so efficient that battery-powered amplified loudspeakers, playing for three hours per day, can run for up to 10 months on a set of four 'C' batteries.
"Sidense's OTP macros combine very low power, a small footprint and ease of programming, which helped Audium develop the most efficient audio power amplifier over normal listening levels in the industry," said Huw Davies, chief commercial officer for Audium, in a statement issued by Sidense.
