1 Introduction
This section provides an overview of the Texas Instruments (TI) TAS2552 Class-D mono speaker amplifier
evaluation module (EVM). It includes a brief description of the module and a list of EVM specifications.
1.1 Description
The TAS2552 is a high efficiency Class-D audio power amplifier with advanced battery current
measurement and an integrated boost converter. It drives up to 3.5 W into an 8-Ωspeaker. The built-in
boost converter generates the Class-D amplifier supply rail. This boosted supply rail provides louder audio
than a stand-alone amplifier directly connected to the battery.
The AGC function automatically adjusts Class-D gain to reduce battery current at end-of-charge voltages,
and prevents output clipping and distortion.
The Class-D output switching is adjustable by the I2C interface, providing a method to slow the Class-D
switching edge rate to improve EMI. For more information about the TAS2552, refer to the datasheet
(SLAS898).
1.2 EVM Specifications
Table 1. EVM Specifications
Boost input supply voltage 2.7 V to 5.5 V

If this is the first time you connect the EVM to a PC, Windows®will install it as a USB HID device.
2.1.1.1 Jumpering Notes
The EVM can run in several input modes:
1. Analog input – Remove all of the jumpers in the JP3 block except for SDA, SCL, and A0. Be sure that
JP4/6 are in the 1 to 2 position and JP5 is not installed. Run the
TAS255x_Analog_Input_Init_Script.cfg script.
2. Digital input from digital interface when attached to a device like an AP PSIA – Remove all of the
jumpers in the JP3 block except for SDA, SCL, and A0. Be sure that jumpers IV CLK, JP DOUT, and
DAT OUT are not installed. Run the TAS255x_I2S_Input_Init_Script.cfg script.
3. Digital input from a PC media player to the digital input of the TAS2552 – Install all of the jumpers in
the JP3 jumper block except for the EN jumper. Be sure that the jumpers IV CLK, JP DOUT, and DAT
OUT are not installed. Run the TAS255x_I2S_Input_Init_Script.cfg script.
2.1.2 Inputs and Outputs
The inputs and outputs for this EVM are described in this section.
2.1.2.1 Audio
1. Verify that the audio source is set to the minimum level.
2. Connect the audio source to the TAS2552-AIN RCA jack located in the top right corner of the EVM
(highlighted in red in Figure 3).
3. Connect an 8-Ωload to the OUT– and OUT+ terminals.
