The TPA6138A2EVM is a customer evaluation module demonstrates the capabilities and operation of the TPA6138A2PW integrated circuit . The TPA6138A2PW is a 25mW Pop Free stereo Head Phone driver designed to replace headphone circuit based on Op amps and passives. The TPA6138A2 doesn't require a power supply greater than 3.3V to generate its 25mW output, nor does it require a split rail power supply. Designed using patented DIRECTPATH technology which integrates a charge pump to generate a negative supply rail that provides a clean, pop free ground biased output. The TPA6138A2 is capable of driving 25mW into 32ohm. DIRECTPATHTM also allows the removal of the costly output DC blocking capacitors. The device has adjustable gain, differential inputs with four gain settings controlled by external resistors to match the line driver with the Codec output level. The TPA6138A2 has built in active mute control with more that 80dB attenuation for pop free mute on/off control.
