Frequently Asked Questions
What is the nominal dynamic range of the TDA1547?
The device has a wide dynamic range of approximately 108 dB (not A-weighted).
How must the TDA1547 be used for optimal audio performance?
It should be used in combination with the SAA7350 bitstream circuit to minimize crosstalk and achieve high fidelity sound reproduction.
What is the purpose of analog ground (AGND) pins?
AGND pins are reference voltage points that must be connected to ensure proper grounding for both switched capacitor DACs and operational amplifiers.
