HEADPHONE OUTPUT CONFIGURATIONS
The headphone output driver is capable of driving up to 2
5mW into a 16Ω or 32Ω load such as a
stereo headset or headphones. The outputs are ground-referenced, eliminating any requirement for
AC coupling capacitors. This is achieved by having separate positive and negative supply rails
