TPA3116D2
SLOS708 FEBRUARY 2012
These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

Terminal Functions
Connect to GND
Shutdown logic input for audio amp (LOW = outputs Hi-Z, HIGH = outputs enabled). TTL logic levels with
compliance to AVCC.
General fault reporting including Over-current_PVCC, OVP_DVDD
FAULTZ = High, normal operation
FAULTZ = Low, fault condition
Positive audio input for right channel. Biased at 3 V.
Negative audio input for right channel. Biased at 3 V.
Power limit level adjust. Connect a resistor divider from GVDD to GND to set power limit. Connect directly
to GVDD for no power limit.
Internally generated gate voltage supply. Not to be used as a supply or connected to any component other
than a 1 F X7R ceramic decoupling capacitor.
Selects Gain and selects between Master and Slave mode depending on pin voltage divider.
Power Ground
Negative audio input for left channel. Biased at 3 V.
Positive audio input for left channel. Biased at 3 V.
Mute signal for fast disable/enable of outputs (HIGH = outputs OFF, LOW = outputs ON). TTL logic levels
with compliance to AVCC.
