TPA6135A2 - Texas Instruments

TPA6135A2 Stereo Headphone Amplifier

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 Ω speakers fr.
