Electrical Characteristics
The following tables list Absolute Maximum Ratings, Recom-
mended DC Characteristics, and recommended AC Charac-
teristics for the APR6008 device.
Absolute Maximum Ratings
Stresses greater than those listed in Table 4 may cause per-
manent damage to the device. These specifications repre-
sent a stress rating only. Operation of the device at these or
any other conditions above those specified in the recom- mended DC Characteristics or recommended AC Character-
istics of this specification is not implied. Maximum conditions
for extended periods may affect reliability.
Table 4 Absolute Maximum Ratings.
ANAIN+ 17 17 19 Non-Inverting Analog Input: This input is the non-inverting input for the analog
signal that the user wishes to record. When the device is used in a differential
input configuration this pin should receive a 16 mV peak to peak input coupled
through a 0.1 uF capacitor. When the device is used in a single ended input con-
figuration this pin should receive a 32 mV peak to peak input coupled through a
0.1 uF capacitor.
/BUSY 21 21 23 Busy Output: This active low output is low during either a record, playback or
fast forward operation. The pin is tri-stated otherwise. This pin can be connected
to an LED to indicate playback/record operation to the user. This pin can also be
connected to an external microcontroller as an indication of the status of play-
back, record, forward, or digital operation.
VCCD 27 27 30, 31, 32 Digital Power Supply: This connection supplies power for all on-chip digital cir-
cuitry. This pin should be connected to the 3.0 V power plane through a via. This
pin should also be connected to a 0.1 uF bypass cap as close to the pin as possi-
ble.
VCCA 18 18 20, 21 Analog Power Supply: This connection supplies power for all on-chip analog
circuitry. This pin should be connected to the 3.0 V power plane through a via.
This pin should also be connected to a 0.1 uF bypass cap as close to the pin as
possible.

Analog Ground: These pins should be connected to the ground plane through a
via. The connection should be made as close to the pin as possible.
VSSD 4 4 5, 6 Digital Ground: This pin should be connected to the ground plane through a via.
The connection should be made as close to the pin as possible.

1, 7, 8, 22 No Connect: These pins should not be connected to anything on the board. Con-
nection of these pins to any signal, GND or VCC may result in incorrect device
behavior or cause damage to the device.
