AiT Semiconductor Inc. www.ait-ic.com A2410 AUDIO AMPLIFIER 10W STEREO CLASS-D AUDIO POWER AMPLIFIER REV2.1 - DEC 2012 RELEASED, SEP 2019 UPDATED - - 7 - 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. PLIMIT Function The voltage at pin “PLIMIT” 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 PLIMIT pin.
