8 Channel Digital Audio PWM Processor

The TAS5548 is an 8-channel Digital Pulse Width Modulator (PWM) with Digital Audio Processing and Sample Rate Converter that provides both advanced performance and a high level of system integration. TAS5548 is designed to support DTS-HD specification Blu-ray HTiB applications. The ASRC consists of two separate modules which handle 4 channels each. Therefore, it is possible to support up to two different input sampling rates. Texas Instruments Power Stages are designed to work seamlessly with the TAS5548. The TAS5548 also provides a high-performance, differential output to drive an external, differential-input, analog headphone amplifier. The TAS5548 supports AD, BD, and ternary modulation operating at a 384-kHz switching rate for 48-, 96-, and 192-kHz data. The external crystal used must be 12.288 MHz. The TAS5548 also features power-supply-volume-control (PSVC), which improves dynamic range at lower power level and can be used as part of a Class G power supply when used with closed-loop PWM input power stages.

The TAS5611A is a high performance analog input Class D amplifier with integrated closed loop feedback technology (known as PurePath™ HD) with the ability to drive up to 125W(1)Stereo into 4 to 8 Ω Speakers from a single 32.5V supply. PurePath™ HD technology enables traditional AB-Amplifier performance (<0.03% THD) levels while providing the power efficiency of traditional class D amplifiers. Unlike traditional Class D amplifiers, the distortion curve only increases once the output levels move into clipping. PurePath™ HD technology enables lower idle losses making the device even more efficient. (1)Achievable output power levels are dependent on the thermal configuration of the target application. A high performance thermal interface material between the package exposed heatslug and the heat sink should be used to achieve high output power levels.

The TAS5612LA is a feature optimized class-D power amplifier based on the TAS5612A. The TAS5612LA uses large MOSFETs for improved power efficiency and a novel gate drive scheme for reduced losses in idle and at low output signals leading to reduced heat sink size. The unique preclipping output signal can be used to control a class-G power supply. This combined with the low idle loss and high power efficiency of the TAS5612LA leads to industry-leading levels of efficiency ensuring a super "green" system. The TAS5612LA uses constant voltage gain. The internally matched gain resistors ensure a high Power Supply Rejection Ratio giving an output voltage only dependent on the audio input voltage and free from any power supply artifacts. The high integration of the TAS5612LA makes the amplifier easy to use; and, using TI’s reference schematics and PCB layouts leads to fast design in time. The TAS5612LA is available in the space-saving, surface-mount, 44-pin HTSSOP package. The TAS5612LA is a feature optimized class-D power amplifier based on the TAS5612A.
