FUNCTION
ACAP

AGC Capacitor
: This pin provides the capacitor connection for
setting the parameters of the microphone AGC circuit. It should
have a 4.7 F capacitor connected to ground. It cannot be
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, or to VCCA gives
minimum gain for the AGC amplifier but will cancel the
AutoMute function.
SP- / SP+
14 / 16
21 / 23
Speaker Outputs
: This differential speaker output is designed
to drive an 8 speaker up to a maximum power of 23.5 mW.
This stage has two selectable gains, 1.32 and 1.6, which can
be chosen through the configuration registers. These pins are
biased to approximately 1.2 VDC and, if used single-ended,
must be capacitively coupled to their load. Do NOT ground the
unused pin.
VCCA / VCCD

Power Supplies
: To minimize noise, the analog and digital
circuits in the ISD5008 device uses separate power busses.
These +3V busses lead to separate pins. Tie the VCCD pins
together as close as possible and decouple both supplies as
near to the package as possible
ANA IN
18
25
Analog Input
: The ANA IN pin is the analog input from the
telephone chip set. It can be switched (by the SPI bus) to the
speaker output, the array input or to various paths. This pin is
designed to accept a nominal 1.11 Vp-p when at its minimum
gain (6dB) setting. See Table 4. There is additional gain
available in 3dB steps controlled from the SPI bus, if required,
up to 15dB.
AUX IN
19
26
Auxiliary Input
: The AUX IN is an additional audio input to the
ISD5008, such as from the microphone circuit in a mobile
phone “car kit.” This input has a nominal 700 mVp-p level at its
minimum gain setting (0dB). See Table 5. Additional gain is
available in 3 dB steps (controlled by the SPI bus) up to 9dB.
AUX OUT
20
27
Auxiliary Output
: 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 and up to a maximum
of 1 Vp-p. The AC signal is superimposed on approximately 1.2
VDC bias and must be capacitively coupled to the load.
