SD OPERATION
The TPA3111D1 employs a shutdown mode of operation designed to reduce supply current (ICC) to the absolute
minimum level during periods of nonuse for power conservation. The SD input terminal should be held high (see
specification table for trip point) during normal operation when the amplifier is in use. Pulling SD low causes the
outputs to mute and the amplifier to enter a low-current state. Never leave SD unconnected, because amplifier
operation would be unpredictable.
For the best power-off pop performance, place the amplifier in the shutdown mode prior to removing the power
supply voltage.
PLIMIT
The voltage at pin 10 can used to limit the power to levels below that which is possible based on the supply rail.
Add a resistor divider from GVDD to ground to set the voltage at the PLIMIT pin. An external reference may also
be used if tighter tolerance is required. Also add a 1mF capacitor from pin 10 to ground.
The PLIMIT circuit sets a limit on the output peak-to-peak voltage. This limit can be thought of as a "virtual"
voltage rail which is lower than the supply connected to PVCC. This "virtual" rail is 4 times the voltage at the
PLIMIT pin. This output voltage can be used to calculate the maximum output power for a given maximum input
voltage and speaker impedance.
Figure 16. PLIMIT Circuit Operation
The PLIMIT circuits sets a limit on the output peak-to-peak voltage. The limiting is done by limiting the duty cycle
to fixed maximum value. This limit can be thought of as a “virtual” voltage rail which is lower than the supply
connected to PVCC. This “virtual” rail is 4 times the voltage at the PLIMIT pin. This output voltage can be used to
calculate the maximum output power for a given maximum input voltage and speaker impedance.
