PIN NAME
PDIP
PIN NO.
FUNCTIONS
V
CCD
1
Digital Power Supply
: It is important to have a separate path for each
power signal including V
CCD
, V
CCA
and V
CCP
to minimize the noise
coupling. Decoupling capacitors should be as close to the device as
possible.
LED
: This output turns on a LED during a record cycle and blinks LED
during playback, forward and erase operations.
RESET
: When Low, the device enters into a known state and initializes all
pointers to the default state. This pin has an internal pull-up resistor
[1]
.
NC:
No Connect.

Analog Ground
: It is important to have a separate path for each ground
signal including V
SSA
, V
SSD
, V
SSP1
and V
SSP2
to minimize the noise
coupling.
AnaIn:
Auxiliary analog input to the device for recording or feed-through.
An AC-coupling capacitor (typical 0.1uF) is necessary and the amplitude
of the input signal should not exceed 1.0 Vpp.
MIC+:
Non-inverting input of the differential microphone signal. The input
signal should be AC-coupled to this pin via a series capacitor. The
capacitor value, together with an internal 10 K
resistance on this pin,
determines the low-frequency cutoff for the pass band filter.
MIC-
: Inverting input of the differential microphone signal. The input signal
should be AC-coupled to the MIC+ pin. It provides input noise-
cancellation, or common-mode rejection, when the microphone is
connected differentially to the device.
Ground for Negative PWM Speaker Driver
: It is important to have a
separate path for each ground signal including V
SSA
, V
SSD
, V
SSP1
and V
SSP2
to minimize the noise coupling.
SP-
: The negative Class D PWM provides a differential output with SP+
pin to directly drive an 8
speaker or typical buzzer. During power down
or recording, this pin is tri-stated.
Power Supply for PWM Speaker Driver
: It is important to have a
separate path for each power signal including V
CCD
, V
CCA
and V
CCP
to
minimize the noise coupling. Decoupling capacitors to V
SSP1
and V
SSP2
should be as close to the device as possible. The V
CCP
supply and V
SSP
ground pins have large transient currents and need low impedance
returns to the system supply and ground, respectively.
SP+:
The positive Class D PWM provides a differential output with the
SP- pin to directly drive an 8
speaker or typical buzzer. During power
down or recording, this pin is tri-stated.
