JAJSKP5A December 2020 – September 2021 TAS2764
PRODUCTION DATA
All typical characteristics for the devices are measured using the Bench Evaluation Module (EVM) and an Audio Precision SYS-2722 Audio Analyzer. A PSIA interface is used to allow the I2S interface to be driven directly into the SYS-2722. Speaker output terminals are connected to the Audio Precision Analyzer analog inputs through a differential-to-single ended (D2S) filter as shown below. The D2S filter contains a first order passive pole at 120 kHz. The D2S filter ensures the TAS2764 high performance class-D amplifier sees a fully differential matched loading at its outputs and the output signal is single ended.
Alternatively, the AUX-0025 filter can be connected directly to the class-D outputs.
