Product Summary
The TPA6132A2RTER is a DirectPath stereo headphone amplifier that eliminates the need for external dc-blocking output capacitors. Differential stereo inputs and built-in resistors set the device gain, further reducing externa component count. Gain is selectable at -6 dB, 0 dB 3 dB or 6 dB. The amplifier drives 25 mW into 16 Ω speakers from a single 2.3 V supply. The applications of the TPA6132A2RTER include Smart Phones / Cellular Phones, Notebook Computers, CD / MP3 Players, Portable Gaming.
