TAS5026APAG Обзор
A digital audio PWM processor is a specialized DSP that converts digital audio streams (e.g., I2S) into pulse-width modulated signals. These PWM signals drive switching power stages, which then feed speakers through passive LC filters. This architecture achieves high efficiency (>90%) compared to linear amplifiers, reducing heat and power consumption in consumer and professional audio equipment.
Key features include six independent channels, I2C control for configuration, and I2S input for digital audio. The device supports sample rates up to 192 kHz and provides advanced processing like volume control and dynamic range compression. Its 64-TQFP package offers a compact footprint for multi-channel designs.
Technically, the TAS5026APAG employs a digital modulator with noise shaping to achieve high signal-to-noise ratio. It is designed to work with TI's PurePath Digital power stages, such as the TAS5121, which can deliver up to 100W into 4Ω speakers. The PWM output is optimized for minimal distortion and jitter.
Typical applications include home theater receivers, AV receivers, soundbars, and active speakers. The device's multi-channel capability and digital interface make it ideal for surround sound systems. It is also used in automotive infotainment and professional audio equipment.
When designing with the TAS5026APAG, ensure proper decoupling of the 3.3V supply and careful PCB layout to minimize noise. The I2C interface allows real-time control of volume and mute functions. Note that the device is now obsolete, so consider alternative parts for new designs.

Заметки по проектированию
The TAS5026APAG requires a clean 3.3V supply. Use a low-noise LDO regulator and place 0.1uF and 10uF decoupling capacitors close to the VDD pins. Avoid sharing the supply with high-current digital circuits to prevent noise coupling into the audio path.
For optimal performance, use a 4-layer PCB with dedicated ground and power planes. Keep the I2S and I2C traces short and shielded to minimize interference. The PWM outputs should be routed away from analog input traces to prevent crosstalk.
Since the TAS5026APAG is obsolete, verify availability and long-term supply before using in production. Also, ensure the external power stage (e.g., TAS5121) is compatible with the PWM output levels. Check the datasheet for proper configuration of the I2C registers.
