APPLICATION EXAMPLE – PASSIVE COMPONENT FUNCTIONS
Part
Function
Comments
R1
Microphone power supply
decoupling
Reduces power supply noise
R2
Release time constant
Sets release time for AGC
R3, R5
Microphone biasing resistors
Provides biasing for microphone operation
R4
Series limiting resistor
Reduces level to prevent distortion at higher supply
voltages.
R6
Series limiting resistor
Reduces level to high supply voltages
C1, C5
Microphone DC–blocking capacitor
Low-frequency cutoff
Decouples microphone bias from chip. Provides single-
pole low-frequency cutoff and common mode noise
rejection.
C2
Attack/Release time constant
Sets attack/release time for AGC
C3
Low-frequency cutoff capacitor
Provides additional pole for low-frequency cutoff
C4
Microphone power supply
decoupling
Reduces power supply noise
C6, C7, C8
Power supply capacitors
Filter and bypass of power supply
In this simplified block diagram of a microcontroller
application, the Push-Button mode and message
cueing are used. The microcontroller is a 16-pin
version with enough port pins for buttons, an LED,
and the ISD2500 Series device. The software can
be written to use three buttons: one each for play
and record, and one for message selection.
Because the microcontroller is interpreting the but-
tons and commanding the ISD2500 device,
software can be written for any functions desired in
a particular application.
NOTE
ISD
does
not
recomend
connecting
address lines directly to a microprocessor
bus. Address lines should be externally
latched.
