DESCRIPTIONAPPLICATIONS The LM4859 is an integrated audio sub-system
designed for stereo cell phone applications.
• Cell PhonesOperating ona 3.3V supply,it combinesa stereo
• PDAs speaker amplifier delivering 495mW per channel into
• Portable Gaming Devices an 8Ω load anda stereo headphone amplifier
delivering 33mW per channel intoa 32Ω load.It
• Internet Appliancesintegrates the audio amplifiers, volume control, mixer,
• Portable DVD/CD/AAC/MP3 Players power management control, and Texas Instruments enhancement all into a single package. In
addition, the LM4859 routes and mixes the stereo
and mono inputs into 10 distinct output modes. The
LM4859is controlled through anI2C compatible
interface. Other features include an ultra-low current
shutdown mode and thermal shutdown protection.
Boomer audio power amplifiers are designed
specificallyto provide high quality output power witha
minimal amountof external components.
The LM4859is availableina 30–bump TL package package.
