3.11.3.3 Speaker Power Output
www.DataSheet4U.com
The maximum power output of the two speakers is not the same due to the
different configurations between Speaker1, which is only single-ended, and
speaker2, which may be differential. Speaker2, thus provides more power.
The maximum specifications given below are available with the maximum
power output configuration values set by AT command.

If a single-ended solution is used with the speaker2 output, only one of the two
SPK2s must be selected. The result is a maximum output power divided by 2.
