TI introduces scalable family of integrated codecs and DACs for enhanced audio features in eBooks

In addition, the devices are pin-to-pin and software compatible, reducing hardware and software development to accelerate time-to-market.

Key features and benefits of the codecs and DACs

* The devices integrate Class-D speaker amplifiers with up to 2.5 W of output power, eliminating the need for multiple resistors and capacitors between the codec and speaker amp for reduced component count and system cost when compared to discrete implementations.
* Pin-to-pin and software compatibility make it easy for manufacturers to develop a common product platform that can generate multiple differentiated end products without having to invest engineering resources to redesign the board or software drivers.
* The products support analog and digital microphones. Customers using digital microphones in conjunction with these devices can achieve up to 10-dB or greater system-level noise immunity versus competitive solutions, critical for a high quality audio experience in portable designs.
* The new devices enable designers to implement enhanced audio features: 3D to increase the spatial sweet spot of compact consumer electronics products; dynamic range compression to automatically adjust the audio to the desired loudness range while protecting the speaker and preventing clipping and distortion; and multiple biquads to equalize the speaker or microphone. In addition, the TLV320AIC3111, TLV320AIC3120 and TLV320DAC3120 integrate a fully programmable miniDSP with up to 50 MIPS, allowing users to write custom algorithms to further differentiate their devices.
