ANAOUT+/–(Analog Outputs)
This differential output is designed to go to the mi-
crophone input of the telephone chip set. It is de-
signed to drive a minimum of 5 k
“+” and “–” pins to a nominal voltage level of
700 mVp-p. Both pins have DC bias of approxi-
mately 1.2 VDC. The AC signal is superimposed
upon this analog ground voltage. These pins can
be used single-ended, getting only half the volt-
age. Do

ground the unused pin.

AUX OUT
The AUXOUT 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 k
up to a maximum of 1 Vp-p. The AC signal is super-
imposed on approximately 1.2 VDC bias and must
be capacitively coupled to the load.

and
SP+, SP–
This is the speaker differential output circuit. It is de-
signed to drive an 8
speaker connected across
the speaker pins up to a maximum of 23.5 mW
power. This stage has two selectable gains, 1.32
and 1.6, which can be chosen through the config-
uration registers. These pins are biased to approxi-
mately 1.2 VDC and, if used single-ended, must be
capacitively coupled to their load. Do
ground the unused pin.

ACAP
This pin provides the capacitor connection for
setting the parameters of the microphone AGC
circuit. It should have a 4.7 μF capacitor con-
nected to ground. It cannot be left floating. This is
because the capacitor is also used in the
playback mode for the AutoMute circuit. This
circuit reduces the amount of noise present in the
output during quiet pauses. Tying this pin to ground
gives maximum gain; to V
for the AGC amplifier but will cancel the AutoMute
function.

To minimize noise, the analog and digital circuits in
the ISD5008 device uses separate power busses.
These +3 V busses lead to separate pins. Tie the
V
CCD
pins together as close as possible and de-
couple both supplies as near to the package as
possible.

SSA
The ISD5008 series utilizes separate analog and
digital ground busses. The analog ground (V
pins should be tied together as close to the pack-
age as possible and connected through a low-im-
pedance path to power supply ground. The
digital ground (V

) pin should be connected
through a separate low-impedance path to pow-
er supply ground. These ground paths should be
large enough to ensure that the impedance be-
tween the V
