Frequently Asked Questions

How much output power does the TPA311DRG4 deliver to a speaker load?

The TPA311DRG4 delivers 0.7 W nominal output power, enough to drive compact 8-ohm speakers in portable devices such as handheld radios, IoT hubs, and educational toys at a clearly audible volume without requiring additional amplification stages.

What is the audio bandwidth of the TPA311DRG4 and which signal frequencies does it cover?

The TPA311DRG4 has a nominal bandwidth of 10 kHz, which covers the essential voice and alert-tone frequency range from sub-100 Hz through 10 kHz, making it well suited for voice announcements, warning beepers, and basic music reproduction in low-cost consumer products.

How does the TPA311DRG4 compare to discrete transistor amplifiers in terms of harmonic distortion?

The TPA311DRG4 achieves 0.5% harmonic distortion at 0.7 W output, which is significantly lower than a typical low-cost discrete BJT amplifier stage, delivering cleaner audio with fewer audible artifacts for voice-quality reproduction in consumer and industrial panel-mount applications.

What package does the TPA311DRG4 use, and is it suitable for reflow soldering?

The TPA311DRG4 is housed in an SO-8 small-outline 8-pin package with plastic/epoxy body, which is fully compatible with standard SMT reflow soldering processes and common PCB footprints, simplifying assembly in high-volume consumer and industrial audio product manufacturing.
