Today’s high-end headsets are designed to offer the best audio experience to listeners even in the most challenging scenarios like hostile weather and noisy streets. Noise cancelling and echo cancellation technology play significant role in improving sound quality in these devices.
To further encourage the production of headsets and other devices with noise cancelling technology, semiconductor technology leader Texas Instruments (News - Alert) (TI) announced the launch of highly integrated audio codec with embedded miniDSP cores offering echo and noise cancellation at wideband voice sampling rates up to 16 kHz.
Based on the third-generation miniDSP technology, the TLV320AIC3262 also offers high-definition voice quality for circuit-switched or VoIP calls, including video conferencing applications. It also includes SRS WOW HD as a standard feature, which is offered free of cost to customers. SRS WOW HD improves audio playback quality and enables faster processing by offloading the duties of the host processor to the codec.
TLV320AIC3262 integrates five amplifiers and two miniDSP cores, so designers get the ability to interface to up to three devices simultaneously, such as application, Bluetooth and baseband processors. The availability of TI audio and voice algorithms, as well as third party algorithms on the codec benefits designers creating multi-purpose and high-definition audio designs for mobile devices.
Additionally, TLV320AIC3262 features three asynchronous audio buses plus asynchronous sampling rate conversion (ASRC) helping designers connect to multiple audio sources and mix multiple sample rates. The intelligent speaker protection algorithms control voice coil temperature and diaphragm excursion to enable maximum possible loudness without damaging the speaker.
The TLV320AIC3262 is available now in a 4.8-mm x 4.8-mm WCSP package, priced at $4.95 in quantities of 1,000. An IBIS model and miniDSP software drivers are also available.
In another recent announcement TI introduced its first 4-A/8-A and 4-A/4-A single-channel, low-side gate drivers with industry-leading speed and drive current capability for minimizing switching loss of MOSFETs, IGBT power devices and wide band-gap power semiconductors, such as gallium nitride (GaN) devices.
