Portable Gaming 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. The high power supply noise
rejection performance and differential architecture
provides increased RF noise immunity. For
single-ended input signals, connect INL+ and INR+ to
ground. …
