OTP memory IP from Sidense drives Audium's power amplifier chip

Sidense's low-power (SLP) one-time programmable (OTP) memory drives Audium's high efficiency AS1001 audio power amplifier IC. 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 Class D power amplifier. Operating from a 1.5V power supply and delivering 100W peak power output, the AS1001 is 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.

"A highly efficient audio power amplifier such as the AS1001 will find use in many consumer products, so minimum power and low cost are essential attributes," said Tom Schild, Vice President of Worldwide Sales for Sidense. "The ultra-low power requirements and very small size of Sidense SLP macros are an ideal fit for Audium's audio power amplifier OTP requirements."

"Optimizing the very high efficiency of our power amplifier ICs requires that every component used on the chips exhibit very low power dissipation," said Huw Davies, Chief Commercial Officer for Audium. "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."
