Stresses greater than 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
maximum rating conditions for extended periods may affect
device reliability.
Ambient Temperature Rating
TAMB = TCASE − (PD × θCA)
where:
TCASE is the case temperature in °C
PD is the power dissipation in W
θCA is the thermal resistance (case-to-ambient)

θJA is the thermal resistance (junction-to-ambient).
θJC is the thermal resistance (junction-to-case).
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
HD AUDIO STYLE JACK PRESENCE DETECTION
The AD1981HD uses two jack sense lines for jack presence
detection. Combined with the peripheral enumeration engines,
this enables software to determine if there is a device plugged
into the circuit and what type of device it is. Software can also
reconfigure jacks and amplifiers as necessary, ensuring proper
audio operation and providing jack retasking.
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 different value resistors
for each jack between the sense line and ground (AVSS). Jacks
must normally have open, isolated switches to use this method
of jack presence detection.
Jack presence is reflected in the HD audio pin widget pin sense
verb. The MSB (Bit 31) indicates the current plugged state of the
connected jack. Jack change interrupts can be enabled using the
unsolicited response verb on each of these nodes. Each jack can
be set to generate a different value to provide event
identification within the software interrupt.
There are two methods to connect the codec to the jack
presence detection pins. In the first method, use a single
2.69 kΩ 1% resistor between the SENSE_A and SENSE_B lines,
but no capacitor. In the second method use a single 2.69 kΩ
resister between SENSE_A and AVDD and between SENSE_B
and AVDD. In the second method, the designer can add up to
1 μF of capacitance on each sense line. Designers should offer
both methods for maximum flexibility.
The specific resistor value for each jack is shown in Table 27.
Use 1% resistors for all jack presence detect circuitry to ensure
accurate detection.
CLASSIC JACK PRESENCE DETECTION
The AD1981HD GPIO pins can be used as classic jack sense
pins in JS_0- and JS_1-style operation (similar to AD1981B
operation). Only two jacks, typically line out and headphone
out, are supported in this configuration. The GPIO pins can be
connected to the left channel wrap-back switch on the jack via a
2.2 kΩ (typical) resistor. The left channel needs a 20 kΩ (typical)
resistor-to-analog ground to complete the circuit. This configuration allows autoconfiguration when other devices are plugged
in; for example, when headphones are plugged in, the external
speakers are disabled for private listening.
