Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute

ESD CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the
human body and test equipment and can discharge without detection. Although this product features
proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy
electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance
degradation or loss of functionality.

JACK PRESENCE DETECTION
The AD1983 uses one jack sense line for presence detection on
up to four external jacks. This enables software to determine if
there is a device plugged into a jack; then, the AD1983 sensing
engine can determine what type of device it is. Jack presence is
detected using a resistor tree arrangement outlined in the HD
Audio specification. Up to four jacks can be sensed on a single
sense line by using a different value resistor for each between
the sense line and ground (AV
SS
). Jacks must have normally-
open, isolated switches to use this method of jack presence
detection.
For proper operation there must be a 2.67 k 1% resistor
connected between SENSE_A and AV
DD
. For this configuration
R1 and C1 should be installed; R2 should not be installed
(see Figure 3).
The specific resistor values for each jack are shown in Table 13.
To ensure accurate detection, use 1% tolerance resistors for all
jack presence circuitry.

An alternate method reduces the current for sensing by
connecting a single 2.67 k 1% resistor between the SENSE_A
and SENSE_SRC pins. For this configuration R1 and C1 are not
installed; however, R2 is installed (see Figure 3).
It is recommended that designers place circuitry for both
sensing methods and only install one of the two options.
