NOTES
REDUCED SUPPORT COMPONENTS
The AD1986A includes many improvements that reduce
external support components for particular applications.
•
•
•
Multiple Microphone Sourcing: The MIC_1/2, LINE_IN
and C/LFE pins can all be selected as sources for
microphone input (boost amplifier).
Multiple VREF_OUT Pins: Each microphone-capable pin
group (MIC_1/2, LINE_IN and C/LFE) has separate,
software controllable VREF_OUT pins, reducing the need
for external biasing components.
Internal Microphone Mixing: Any combination of the
MIC_1/2, LINE_IN and C/LFE pins can be summed to
produce the microphone input. This removes the need for
external mixing components in applications that externally
mix microphone sources.

Advanced Jack Presence Detection: Using two codec pins,
eight resistors and isolated switch jacks, the AD1986A can
detect jack insertion on eight separate jacks.
Internal Microphone/Line In/C/LFE Sharing: On
systems that share the microphone with the C/LFE jack no
external components are required. The microphone
selector can select the LINE_IN pins when the microphone
and line input devices are swapped.
Internal Line In/Microphone/Surround Sharing: On
systems that share the line in with the surround jack no
external components are required.
Dual Headphone Amplifiers: The AD1986A can drive
headphones out of the HP_OUT or LINE_OUT pins.
