Stereo Evaluation Module Reference Design of the Digital Input: Class-D: IV Sense Audio Amplifier(TIDA-01572)

This reference design provides a high-performance stereo audio subsystem for use in PC applications. It operates off a single supply, ranging from 4.5 V to 16 V, and features the TAS2770, a digital-input Class-D audio amplifier that provides excellent noise and distortion performance and is available in both WCSP and QFN packages. The design also includes two low-dropout fixed voltage regulators, the TL760M33 and TPS73618, which generate the necessary 3.3 V and 1.8 V system rails, respectively. The reference design’s versatile digital-input interface allows for a wide variety of input formats, while providing output data for voltage and current sense, supply voltage (VBAT) and temperature. The reference design also includes multiplexing to allow multiple input sources to the digital inputs. Additionally, the TAS2770 incorporates an automatic gain controller that can track VBAT to limit the output voltage, as desired. This function can help extend the battery life of battery-powered applications, such as laptops and tablets, and prevent system-level brownout. Inter-chip limiter alignment can be configured on multiple TAS2770 devices to coordinate limiter activity using a shared digital output. This will ensure that the entire system maintains comparable gain levels at all times to provide the best listening experience.
