Bangalore, Aug. 9
Semiconductor firm Analog Devices has introduced two Class-D audio amplifiers for portable electronics. The firm is designing its Class-D amplifiers to address the space constraints and battery-consumption requirements of cellular handsets, handheld game machines, MP3 players, laptop computers and handheld media devices.
The SSM2301 and SSM2304 Class D amplifiers are designed to efficiently drive speakers in handheld and portable consumer applications by consuming minimal power, employing sigma-delta modulation to reduce electromagnetic interference emissions and integrating a filterless topology that eliminates external components. The ability to function at very low voltages makes them ideal for applications such as cellular handsets, where the speaker amplifiers are driven directly from the battery voltage, said the release issued by the company.
These amplifiers are priced at $0.55 per unit in 1,000-piece quantities.
