FUNCTIONS
V
CCA
10
Analog power supply
: It is important to have a separate
path for each power back to the power terminal to minimize
the noises. Decoupling capacitors to V
SSA
should be as
close to the device as possible.
V
CCP
: Power supply for PWM speaker drivers. It is important
to have a separate path for each power back to the power
terminal to minimize noise. Decoupling capacitors to V
SSP
should be as close to the device as possible.
Speaker Positive
: The SP+, Class D PWM output, provide
a differential output with SP- pin to drive an 8
speaker or
buzzer directly. During power down or recording, this pin is
tri-stated.

AGC
12
Automatic Gain Control
: The AGC dynamically adjusts the
gain of the preamplifier to compensate the wide range of
microphone input levels. The AGC allows the full range of
signal to be recorded with minimal distortion. Nominal
values of 4.7 μF give satisfactory results in most cases.
Connecting this pin to ground provides maximum gain to the
preamplifier circuitry. Conversely, connecting this pin to
power supply provides minimum gain to the preamplifier
circuitry.
AUD
13
AUD
: The AUD provides a single-ended current output to
drive an external amplifier. During standby or recording, this
pin is tri-stated.
R
OSC
14
Oscillator Resistor
: This enables the user to vary the
record and/or playback duration of the device. A resistor
connected between the R
OSC
pin and V
SSA
determines the
sample frequency for the ISD1600B device. Please refer to
the Duration Section in Section 6.1.
V
CCD
15
Digital power supply
: It is important to have a separate
path for each power back to the power terminal to minimize
noise. Decoupling capacitors should be as close to the
device as possible.
LED
output
: This pin is Low during a record cycle and
blinks during playback cycle. It can be used to drive an LED
to indicate either a record or playback cycle is in progress.
