DETAILED INFORMATION
Shutdown Operation
The A2410 supports shutdown mode. The SDb input terminal should be held high during normal operation
when the amplifier is in use. Pulling SDb low to enter shutdown mode
PBTL Select
A2410 offers the feature of parallel BTL operation with two outputs of each channel connected directly. If the
PBTL pin is tied high, the positive and negative outputs of each channel (left and right) are synchronized and
phase.
To operate in this PBTL mode , apply the input signal to the Right input and place the speaker between the
Left and Right outputs. Connect the positive and negative output together for best efficiency.
PLIMT Function
The voltage at pin “PLIM” can used to limit the power to levels below that which is possible on supply rail.
Add a resistor divider from AVCC to ground to set the voltage at the PLIM pin.

Short Circuit Protection
The A2410 has short-circuit protection circuitry on the outputs to prevent damage to the device during
output-to-output shorts. The short-circuit protection includes an auto-recovery feature.
