Frequently Asked Questions
What output power and THD does the TDA8551T/N1,112 Class-AB amplifier deliver into a standard speaker load?
The TDA8551T delivers approximately 1 W of output power into an 8 Ω load with a total harmonic distortion (THD) of 0.15%, providing clean, high-fidelity mono audio suitable for portable speaker and headphone driving applications.
What supply voltage range does the TDA8551T/N1,112 support, and which battery chemistries are compatible?
The TDA8551T operates from a single supply spanning 2.7 V to 5.5 V, covering single-cell Li-ion batteries at 3.7 V nominal, regulated 3.3 V rails, and standard 5 V USB supplies, making it versatile for portable consumer audio and handheld multimedia devices.
How does the TDA8551T integrated volume control reduce design complexity compared to a discrete audio amplifier stage?
The built-in digital volume control removes the need for a separate potentiometer or external attenuator IC, cutting BOM cost and saving PCB area while enabling software-controlled audio level adjustment directly through the 8-pin SOIC device with minimal external passive components.
