TAS5548/58 8-Channel HD Audio Processors

Texas Instruments TAS5548 and TAS5558 HD-compatible audio processors are 8-channel digital Pulse-Width Modulators (PWMs) with digital audio processing and sample rate converters that provide both advanced performance and a high level of system integration. TI TAS5548 and TAS5558 are designed to interface seamlessly with most digital audio decoders. The devices support DTS-HD specification for Blu-ray HTiB applications. The sample rate converters consist of two separate modules that handle 4 channels each. TAS5548 and TAS5558 can support two different input sampling rates. These TI devices can drive 8 channels of H-bridge power stages. They also provide a high-performance, differential output to drive an external, differential-input, analog headphone amplifier.
