The A7023 is the new stereo Class-D audio amplifier capable of supporting up to 6.5V operation allowing device manufacturers to build standard 6V battery powered; both standard battery and the rechargeable devices with Class-D audio capability. The A7023 is targeted for the portable and semi-portable applications, incorporating multi-media speakers, small-sized LCD monitors, notebooks, MIDs, digital photo frames, GPS, MP3 and PMP players.
Portable audio device makers are looking for IC amplifier solutions that deliver audio and multimedia experiences on these portable devices working with up to 6.5V voltage operation from four AA-size batteries or regular electrical chargers, said Jeff Yang, Apexone’s sales manager of audio product line. Our new stereo chip enables these voltage applications with our patent pending technologies and architecture, plus the added digital volume controlled function. The device is specially designed to work with 6.5V CMOS voltage over a commercial 5V standard CMOS process, which perfectly creates the cost effectiveness to support the working voltage requests.
The new stereo class-D amplifier solution is targeted for portable applications adds 6.5V of 4-battery working voltage capabilities, the digital volume tuning functionality, extended battery life and improved stereo sound clarity. All of these superior capabilities are delivered on a SOP16 or SOP20 package that saves the cost and space.
Our new A7023 demonstrates Apexone’s commitment to developing unique audio amplifier chip products that offer leading performance, leading efficiencies, leading designs over the complete application lines, said Amy Ren, Apexone’s senior engineering manager of audio product line . In the coming months, we’ll continue to introduce new audio products that will extend our advantage as the audio IC supplier of the key products focusing next generation mobile and portable devices.
Technical Information:
The fast startup time, low shutdown current and small package size of A7023 make it ideal choice for powered speakers and portable devices. The A7023 can drive the speakers as low as 4-ohm or even lower.
The new A7023 is available in restriction of hazardous substances (RoHS) compliant and 100% lead (Pb)-free SOP20 and the SOP16 packages. The new A7023 is specified over the -40°C to +85°C temperature range.
