STMicroelectronics Launches Flip-chip Stereo Headset Amplifier

(Product News, 18 Feb 2008)

STMicroelectronics has released TS4601, a stereo headset amplifier optimized for feature-phone applications that improves audio performance, extends battery life and enables responsive user controls compared to existing solutions. The TS4601's power-supply rejection ratio of -107dB (typical) prevents noise from the handset battery from reaching the audio output. As a result, the overall audio quality provided is close to that of a dedicated hi-fi system, while savings in overall current consumption allow end products to provide longer listening times and more functions for a given battery size. The sub 2µA stand-by mode is a further aid to frugal power management.

The low-profile flip-chip package measuring 2.1x2.1x0.6mm allows designers to take advantage of the TS4601's enhanced features to create sleek, high-end mobile handsets offering advanced music features. The TS4601 can be used in many other portable and consumer products demanding high audio capabilities and system-level performance advantages, including MP3 players and notebook computers. User functions and configuration control are managed via the device's built-in I²C interface, enabling enhanced flexibility and an improved user experience compared to other devices on the market.
