The Texas Instruments TAS5615 and TAS5616 are Class D amplifiers with PurePath™ HD closed loop feedback technology. The TI TAS5615 is an analog-input Class D amplifier while the TI TAS5616 is a digital-input (PWM) Class D amplifier. Both TI devices feature signal bandwidth up to 80 kHz for high frequency content from HD sources. The PurePath HD technology in the TAS5615 and TAS5616 enables traditional AB-Amplifier performance levels while providing the power efficiency of traditional Class D amplifiers.
