Phoenix, Ariz. – April 15, 2004 – Continuing its campaign to introduce advanced system solutions that enable designers to deliver differentiated portable products, ON Semiconductor (Nasdaq: ONNN) today introduced the NCP2809 – a cost effective stereo audio amplifier that improves sound quality and reduces part count in space-restricted wireless applications such as cell phones and portable music and game players.
Because the NCP2809 delivers 135 milliwatts (mW) to a 16 ohm load from a 2.5 volt (V) to 5.5 V Li-ion battery supply, it is ideal for low power portable audio equipment. The device’s ultra-low shutdown current and sleep mode features optimize power consumption for extended battery life. Excellent power supply rejection ratio (PSRR) and a virtual ground between the stereo speakers eliminates the need for bulky DC-blocking output capacitors. This simplifies design and reduces system cost. Outstanding Total Harmonics Distortion plus Noise (THD+N) as low as 0.01 percent provides high-quality audio for wireless headset applications. The device is offered with either an adjustable or fixed 0 decibel (dB) gain depending on the specific needs of the designer.
“High quality stereo audio is an important selling feature within the competitive cell phone, portable music and handset game markets,” said Andy Khayat, ON Semiconductor marketing director for portable products. “Through the integration of key features, the NCP2809 addresses the growing portable industry demand for audio amplification that extends battery life, minimizes board space and lowers total circuit cost while still maintaining superior audio performance.”
The NCP2809 is offered in a Micro-10 package in two different options (adjustable or fixed 0 dB gain) and priced at $0.50 per unit in 10,000 unit quantities.
