WM8959
Pre-Production
The outputs LON, LOP, RON and ROP are capable of driving line loads only. Single ended output is
possible on all these output simultaneously. Differential output is also possible between LOP and
LON and between ROP and RON.
Typical applications for the line outputs (single-ended or differential) are:
•
•
•
Handset or headset microphone output to external voice CODEC
Stereo line output
Output to external speaker driver(s) to support stereo loudspeakers
Some example line output configurations are shown below.
