资 源 简 介
The TPA6136A2 (someTImes referred to as TPA6136) 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 TPA6136A2 (TPA6136) provides a constant maximum output power independent of the supply voltage, thus facilitaTIng the design for prevenTIon of acoustic shock.
The TPA6136A2 (TPA6136) features fully differential inputs with an integrated low pass filter to reduce system noise pickup between the audio source and the headphone amplifier and to reduce DAC out-of-band noise.
