Chapter 1 Introduction This chapter provides an overview of the Texas Instruments (TI) TPA4411 capless stereo headphone amplifier evaluation module. It includes a brief description of the module and a list of EVM specifications. Topic Page Description ...........
Description 1.1 Description The TPA4411 is a capless stereo headphone amplifier capable of delivering 80 mW/Ch without the added output DC blocking capacitors. The TPA4411 EVM includes connections for input, power, ground, pushbuttons, and a head- phone jack for the outputs.
This means that a low voltage (ground) on this pin will place the appropriate channel in shutdown mode. Using the pushbuttons provided on the EVM, the TPA4411 can be placed in shutdown by pressing and holding the button(s) down. Both buttons must be depressed in order for both channels of the TPA4411 to turn off.
