TPA3244, High-Perfomance, Class-D Amplifier
Texas Instruments offers its TPA3244, 60 W stereo, 110 W peak PurePath™, Ultra-HD, analog-in, pad-down, Class-D amplifier
Texas Instruments' TPA3244 device is a high-performance Class-D power amplifier that enables true premium sound quality with Class-D efficiency. It features an advanced integrated feedback design and proprietary high-speed gate driver error correction (PurePath Ultra-HD). This technology allows ultra-low distortion across the audio band and superior audio quality. With a 30 V power supply, the device can drive up to 2 x 110 W peak into a 4 Ω load and 2 x 60 W continuous into an 8 Ω load and features a 2 VRMS analog input interface that works seamlessly with high-performance DACs, such as the Burr-Brown PCM52xx DAC family from TI (that is, PCM5242 / PCM5252). In addition to excellent audio performance, the TPA3244 achieves both high power efficiency and very-low power stage idle losses, below 0.45 W. This is achieved through the use of 65 mΩ MOSFETs and an optimized gate driver scheme that achieves significantly lower idle losses than typical discrete implementations.
