Advanced Information
PRELIMINARY
SP +, SP- (Speaker +/-)
This is the speaker differential output circuit. It is designed to drive an 8Ω speaker connected across
the speaker pins, up to a maximum of 23.5 mW RMS power. This stage has two selectable gains, 1.32
and 1.6, which can be chosen through the configuration registers. These pins are biased to ap-
proximately 1.2 VDC and, if used single-ended, must be capacitively coupled to their load. Do NOT
ground the unused pin.
AUX OUT (Auxiliary Output)
The AUX OUT is an additional audio output pin to be used, for example, to drive the speaker circuit in
a “car kit.” It drives a minimum load of 5 kΩ and up to a maximum of 1 V p-p. The AC signal is
superimposed on approximately 1.2 VDC bias and must be capacitively coupled to the load.
