O O(DF)
Speaker Analog Output. The ASPKR analog output can originate from one
of five different sources: RIN, TELIN, MICM or MICV or from the MDP’s
internal voice playback mode. The ASPKR on/off and three levels of
attenuation are controlled by bits in DSP RAM. When the speaker is turned
off, the ASPKR output is clamped to the voltage at the VC pin. The ASPKR
output can drive an impedance as low as 300 Ω. In a typical application, the
ASPKR output is an input to an external LM386 audio power amplifier.
