Stereo audio codec

A new stereo audio codec providing higher-quality audio and reduced power is now available from Texas Instruments. The TLC320AD90 is fully compliant with the Audio Codec (AC) '97 specification, providing PC motherboard and add-in card vendors an audio solution that exceeds the parameters affecting true audio quality.

The device, which also provides an integrated 600-ohm power amplifier not specified in the standard, is well-suited for applications such as video and audio conferencing, musical instruments and high-end video cards.

The 'AD90 provides CD-quality conversion, analog mixers, volume control and has a pseudo-differential CD input to offer improved CD-ROM analog performance. Additional features include a 5-V or 3.3-V digital interface, allowing the device to interface to 5-V or 3.3-V controllers, and a power-down mode to conserve power.

The TLC320AD90 is now available from TI and authorized distributors.

Suggested resale pricing in U.S. dollars in 1K quantity.
