TPA6138A2 Description
The TPA6138A2 is a pop-free stereo headphone amplifier designed to allow the removal of the output dc-blocking capacitors for reduced ponent count and cost. The device is ideal for single-supply electronics where size and cost are critical design parameters. Designed using TI’s patented DirectPath™ technology, The TPA6138A2 is capable of driving 25 mW into a 32-Ω load with 3.3-V supply voltage.
