ISD1600B SERIES  
PIN NAME  
SOIC / PDIP  
PIN NO.  
10  
FUNCTIONS  
VCCA  
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 VSSA should be as  
close to the device as possible.  
VCCP  
SP+  
10  
11  
VCCP: 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 VSSP  
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 8speaker 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  
ROSC  
13  
14  
AUD: The AUD provides a single-ended current output to  
drive an external amplifier. During standby or recording, this  
pin is tri-stated.  
Oscillator Resistor: This enables the user to vary the  
record and/or playback duration of the device. A resistor  
connected between the ROSC pin and VSSA determines the  
sample frequency for the ISD1600B device. Please refer to  
the Duration Section in Section 6.1.  
VCCD  
15  
16  
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.

Note: [1] 600kΩ (typical).
