Frequently Asked Questions
What is the output power and channel configuration of the TPA311DGNG4?
The TPA311DGNG4 is a mono (single-channel) audio power amplifier with a nominal output power of 0.7W and a rated output of 0.35W. It supports a bandwidth of up to 10 kHz and delivers 0.5% total harmonic distortion, making it suitable for compact, low-power audio designs.
What are the typical applications for the TPA311DGNG4?
The TPA311DGNG4 is commonly used in portable consumer electronics such as smartphones, Bluetooth speakers, handheld gaming devices, and tablets. Its low-power single-channel design also makes it a strong candidate for toys, wearable audio devices, and embedded systems requiring efficient audio amplification.
What package does the TPA311DGNG4 come in and what does the G4 suffix mean?
The TPA311DGNG4 uses the S-PDSO-G8 package, which is a standard 8-pin Small Outline Package (MSOP-8 form factor). The 'G4' suffix in the part number indicates the device complies with JESD-609 e4 halogen-free and RoHS-compliant requirements, reflecting Texas Instruments' green packaging standards.
How does the TPA311DGNG4 compare to other TI audio amplifier alternatives?
Compared to similar TI amplifiers like the TPA301 and TPA2005D1, the TPA311DGNG4 offers a balance of low THD (0.5%) and compact packaging in a price-competitive range starting at $0.79. For higher output power requirements, TI's TPA2025D1 (2.1W) or TPA2012D2 (stereo) may be considered as alternatives.
