description
The TPA302 is a stereo audio power amplifier capable of delivering 250 mW of continuous average power into
an 8-鈩?load at less than 0.06% THD + N from a 5-V power supply or up to 300 mW at 1% THD + N. The TPA302
has high current outputs for driving small unpowered speakers at 8
鈩?/div>
or headphones at 32
鈩?
For headphone
applications driving 32-鈩?loads, the TPA302 delivers 60 mW of continuous average power at less than 0.06%
THD+ N. The amplifier features a shutdown function for power-sensitive applications as well as internal thermal
and short-circuit protection. The amplifier is available in an 8-pin SOIC (D) package that reduces board space
and facilitates automated assembly.
