The TPA6135A2 (someTImes referred to as TPA6135) 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 external component count. Gain is selectable at 0 dB or 6 dB. The amplifier drives 25 mW into 16 speakers from a single 2.3 V supply. The TPA6135A2 (TPA6135) provides a constant maximum output power independent of the supply voltage, thus facilitaTIng the design for prevenTIon of acoustic shock.
The TPA6135A2 (TPA6135) features HI-Z mode which can set the outputs to a high impedance configuration. The fully differential inputs reduce system noise pickup between the audio source and the headphone amplifier.
