The Texas Instruments TPA102 is a stereo audio power amplifier designed for applications requiring efficient audio amplification. Packaged in an 8-pin PowerPAD MSOP, it delivers 150 mW of continuous RMS power per channel into 8-ohm loads.
This amplifier is fully specified for operation at 3.3 V and 5 V, making it versatile for various power supply designs. It includes features such as pop reduction circuitry and internal mid-rail generation, simplifying external component requirements. The TPA102 also incorporates thermal and short-circuit protection for enhanced reliability.
Gain is externally configurable via resistors, allowing for settings from 1 to 10 without requiring external compensation. Performance metrics include low THD+N, with values as low as 0.01% at 1 kHz for 10-k loads and less than 2% across the audio band for 8-ohm loads from a 5V supply.
The surface-mount HVSSOP (DGN) package has an area of 14.7 mm² and dimensions of 3 mm x 4.9 mm. It is also MSOP pin compatible with the LM4881.
