LOUDSPEAKER AMPLIFIERS ALSPR AND ALSPL
a set of low ohmic loudspeakers for speakerphone, ringing
and music playback modes. The amplifiers are powered
directly by the main battery and include a feedback system in
order to reach a high PSRR performance. The amplifiers run
at a frequency around 3.0 MHz. The outputs are half rail

referenced. The feedback networks of the Alsp amplifiers are
fully integrated. The right channel amplifier is enabled by
setting the PSCNTSPR bit, the left channel amplifier by the
PSCNTSPL bit. When enabled, the right and left channel
audio paths are routed to their respective amplifiers. The
output signal can be muted by setting the MUTSPKR and
MUTSPKL bits.

channel audio is routed to the HSR output and the left
channel audio to the HSL output. The output signal can be
muted by setting the MUTHPR and MUTHPL bits.
