Description
General part information
TPA3139D2 Series
The TPA3139D2 is a 10-W stereo Class-D audio amplifier, featuring a fast turn-on time of <15 ms and mute function. It consumes low idle current of only 20-mA (12-V) and can operate down to 3.5-V, allowing for longer audio playback. Along with a small, 4 x 4 mm2QFN package, the TPA3139D2 is optimized for 2-cell or 3-cell battery-powered systems with the space constraints. In addition, the Spread Spectrum Control enables the use of inexpensive ferrite bead filters while meeting EMC requirements for system cost reduction.
To further simplify the design, the TPA3139D2 integrates essential protection features including undervoltage, overvoltage, power limit, short circuit, overtemperature, as well as DC speaker protection. All of these protections support automatic recovery.
