Texas Instruments (TI) has announced a stereo amplifier that the company said boosts the audio quality of ultrabooks, Bluetooth speakers, and tablet and ultrabook docking stations. The TPA3131D2 is the industry's first Class-D amplifier to deliver 7W from a miniature QFN package and produces more than three times the power output compared to high definition audio (HDA) codecs, and it's half the package size of discrete amplifiers with comparable output, while delivering longer standby battery life, boasted the firm.

The TPA3131D2 touts up to 92 per cent power-efficient Class-D operation, and less than 50uA quiescent power consumption allows for longer standby battery life compared to discrete amplifiers in larger TSSOP packages. Additionally, the device offers low power rail of 4.5V, compared to 8V for integrated amplifiers. Supply range extends to 26V to support both AC-powered and 2S battery-configured systems. It also combines with the TLV320AIC3254 stereo audio codec with miniDSP, and the TPA6132A2 stereo headphone amplifier to create a high-performance audio solution. added TI.

The TPA3131D2EVM can be purchased for a suggested retail price of $149. PSpice models are also available for verifying board signal integrity requirements.

The TPA3131D2 is available in a 32-pin QFN package for a suggested retail price of $1.10 in 1,000-unit quantities.
