5. PIN DESCRIPTION
[1]
connected to this pin can drive a load as small as 5 KΩ. When in record, a built-in resistor connects AUD OUT to
the internal 1.2-volt analog ground supply. This resistor is approximately 850 KΩ, but will vary somewhat
according to the sample rate of the device. This relatively high impedance allows this pin to be connected to an
audio bus without loading it down.

Slave Select: This input, when LOW, will select the
ISD4003 device.
Master Out Slave IN: This is the serial input to the
ISD4003 device when it is configured as slave. The master
microcontroller places data on the MOSI line one half-cycle
before the rising edge of SCLK for clocking into the device.
Master In Slave Out: This is the serial output (open drain)
of the ISD4003 device. This output goes into a high-
impedance state if the device is not selected.
Ground: The ISD4003 series utilizes separate analog and
digital ground busses. The analog ground (V
should be tied together as close as possible and connected
through a low-impedance path to power supply ground.
The digital ground (V
a separate low-impedance path to power supply ground.
These ground paths should be large enough to ensure that
the impedance between the V
less than 3 Ω. The backside of the die is connected to V
through the substrate. For chip-on-board design, the die
attach area must be connected to V

Audio Output: This pin provides an audio output of the
stored data and is recommended be AC coupled. It is
capable of driving a 5 KΩ impedance R
