Flip-Chip Stereo Headset Amplifier from STMicroelectronics Brings Premium Handhelds Closer to Audio Nirvana
STMicroelectronics announced the TS4601, a stereo headset amplifier optimized for feature-phone applications that improves audio performance, extends battery life and enables more responsive user controls compared to existing solutions.
Low power, low distortion, and enhanced user controls enable virtuoso performance for music on the go
STMicroelectronics has announced the TS4601, a stereo headset amplifier optimized for feature-phone applications that improves audio performance, extends battery life and enables more responsive user controls compared to existing solutions.
The TS4601’s class-leading 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 2-microamp stand-by mode is a further aid to frugal power management.
The low-profile flip-chip package measuring 2.1×2.1×0.6mm 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.
