2.2 Quick Start List for Platform

Follow these steps when using the TPA005D12 class-D EVM with the TI plug-n-play audio amplifier evaluation platform (see the platform user's guide, SLOU011, for additional details). Numbered callouts for selected steps are shown in Figure 2±1 and details appear in Chapter 3.

-Platform Preparations

1)Ensure that all external power sources are set to OFF.

2)Install a TPA005D12 module in platform socket U2, taking care to align the module pins correctly (EVM power pins engage sockets U2 and U3).

3)Set switch S2 to OFF.

4)Set switch S3 to U5.

5)Set jumper JP6 to select the Mute control input.

6)Set control signal Polarity jumper JP8 to Lo.

2)Unregulated and battery sources must have a voltage regulator EVM (SLVP097) installed in platform socket U6.

3)Set to ON when tone control board SLOP109 is installed in U1.

-Power supply

7)Connect a 5-Vregulated power supply (ensure power supply is set to OFF ) to J6, taking care to observe marked polarity.

8)Set jumper JP5 for VDD power to EVMs.

-Inputs and outputs

9)Ensure that the audio signal source level is set to minimum.

10)Connect the audio source to left and right RCA phono jacks J3 and J5 or stereo miniature phone jack J4.

11)Connect 4-Ω± 8-Ωspeakers to left and right RCA jacks J7 and J9 or to stripped wire speaker connectors J8.

-Power up

12)Verify correct voltage and input polarity and set the external power supply to ON.

Platform LED2 should light indicating the presence of VDD, and the evaluation module(s) installed on the platform should begin operation.

13)Set switch S2 to ON if tone control board SLOP109 is installed in U1.

14)Adjust the signal source level as needed.

TPA005D12 specifications

The Texas Instruments TPA005D12 is a highly regarded digital audio power amplifier that is engineered for high-performance applications. It is part of TI's TPA series, which is known for its efficient power delivery and superior sound quality. The TPA005D12 is designed to drive passive speakers while ensuring minimal power loss and efficient heat management.

One of the standout features of the TPA005D12 is its ability to provide 5 watts of continuous output power per channel into an 8-ohm load with a low total harmonic distortion (THD) rating. This makes it suitable for use in a variety of audio applications, including computer speakers, soundbars, and portable audio systems. The amplifier operates from a single supply voltage, ranging typically from 4.5V to 14V, allowing for flexible integration into different power supply environments.

The TPA005D12 adopts Class-D amplification technology, which significantly enhances power efficiency compared to traditional linear amplifiers. Class-D amplifiers convert the input audio signal into a series of pulse-width modulated signals, resulting in increased power savings and reduced heat generation. This not only improves the overall energy efficiency but also contributes to a longer operational lifespan for devices utilizing this technology.

Additionally, the TPA005D12 features an integrated thermal and short-circuit protection mechanism, which helps safeguard the amplifier from potential damage due to excessive temperatures or electrical faults. This reliability factor is crucial for manufacturers looking to create robust consumer electronics.

Another important characteristic is its integrated low-noise power supply rejection ratio (PSRR), which helps maintain sound clarity and reduces the impact of power supply noise on audio quality. The TPA005D12 also supports differential input signals, which can improve common-mode noise rejection and further enhance audio performance.

The device is offered in a compact package suitable for space-constrained applications, enabling easy integration into various designs. With a combination of low cost, high efficiency, and excellent audio performance, the Texas Instruments TPA005D12 stands out as a top choice for developers and engineers seeking reliable audio amplification solutions. Whether in home entertainment systems or personal audio devices, the TPA005D12 is designed to deliver exceptional sound quality with a minimal footprint.
