TAS5756M数据手册开发板套件编程器的评估板-音频放大器规格书PDF

描述 Description

The TAS5756M device is a high-performance, stereo closed-loopamplifier withintegrated audio processor with architecture. To convertfrom digital toanalog, the device uses a high performance DAC withBurr-Brown mixed signalheritage.It requires only two power supplies; one DVDD for low-voltagecircuitry and one PVDD forhigh-voltage circuitry. It is controlled by asoftware control port using standardI2C communication. In thefamily, theTAS5756M uses traditional BD modulation, ensuring low distortioncharacteristics. The TAS5754M uses1SPW modulation to reduce output ripplecurrent, the expense of slightly higher distortion.The unique HybridFlow architecture allows the system designer tochoose fromseveral configurable DSP programs that are specifically designed for use inpopularaudio end equipment such as bluetooth (BT) speakers, sound bars,docking stations, and subwoofers.This architecture combines the flexibility ofa fully programmable device with the fast downloadtime and ease of use of afixed-function ROM device. An optimal mix of thermal performance and device cost is provided in the90mΩ rDS(on) of the output MOSFETs. Additionally, athermally enhanced48-Pin HTSSOP provides excellent operation in the elevated ambienttemperaturesfound in modern consumer electronic devices. For all availablepackages, see the orderable addendum at the end of the datasheet. Pleaserefer to SLAU577 for information regarding Audio Processing optionsavailable via the HybridFlow library.Tested on TAS5756MDCAEVM.
