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.

AD1983 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 (AVSS). Jacks must have normallyopen, 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 AVDD. 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. Table 13. Jack Sense Mapping
SENSE_A Resistor (1%) 5.1 k 10.0 k 20.0 k 39.2 k Name Line Out Line In Microphone Headphone Out Port D C B A Node ID (Hex) 05 09 08 06
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.
