Texas Instruments Inc. introduces its second-generation, 15W stereo analog-input Class-D amplifiers with single-ended outputs. These devices, claims TI, eliminate components to reduce total solution size and cost in HDTVs and other consumer audio electronics. Innovative features address single-ended design challenges to ensure robust and reliable audio performance in LCD, plasma and DLP TVs and other home audio products.

The devices leverage TI's technology to solve the click and pop challenges typically associated with single-ended solutions. Along with single-ended stereo support, the TPA3121D2 and TPA3124D2's outputs can be configured in BTL mode to support 30W mono applications, such as wireless speakers or subwoofers. In addition, the TPA3124D2 features a fast mute time of 30?s.

The TPA3121D2 and TPA3124D2 join TI's offering of single-ended audio solutions for HDTVs and consumer audio electronics. In addition, to address the market shift toward I2S inputs, TI offers digital-input, closed-loop Class-D solutions such as the recently released TAS5706.

The TPA3121D2 and TPA3124D2 are available now. For more information, visit or
