TPA6132 Differential-Balance Headphone Amplifier Board with Socket

Build your own stereo preamplifer or build a compact headphone amplifier with the TPA6132 HiFi Headphone Amplifier Board from PMD Way.

It's perfect for taking a stereo line-level audio signal and boosting it for your headphones, or connection to a power amplifier for speaker output.

It is a minimalist board that run on only 2.3~5.5V DC and still offer 15~25mW of power into your headphones. Using the board is simple as all pinouts are labelled on the PCB. The board is designed for a single-rail power supply (just negative and positive).

Furthermore the 3.5mm stereo jack is soldered to the board. Two interesting functions are included - the DET pin is logic-high when headphones are connected and logic-low when the socket is empty; CTRL pin is used for an external device (such as audio source) to turn the headphone amp on and off to help save power.
