TAS5001PFBRG4 - Digital Audio PWM Processor | TI | 48-TQFP
The TAS5001PFBRG4 is a true digital audio amplifier digital audio PWM processor from Texas Instruments, designed for high-quality digital audio amplification. It is housed in a 48-pin TQFP (7x7 mm) package and operates as a 2-channel audio signal processor. The device delivers a 96-dB dynamic range and a THD+N of 0.08% at 1 kHz, making it suitable for demanding audio applications. A digital audio PWM processor is a specialized integrated circuit that converts digital audio data (such as I2S or TDM) into a pulse-width modulated (PWM) signal that can directly drive a class-D power stage. This approach enables efficient, high-fidelity amplification by keeping the audio signal in the digital domain until the final output stage, minimizing analog distortion and noise. The TAS5001 is part of the broader class of digital audio amplifiers, which are essential in modern consumer electronics, automotive infotainment, and professional audio equipment. Key features of the TAS5001PFBRG4 include a 96-dB dynamic range, 0.08% THD+N at 1 kHz, and support for 2-channel audio processing. The device is designed to work with the TAS5100 power stage to form a complete digital amplifier system, achieving a system-level dynamic range of 93 dB measured at the speaker terminals. The PWM processor handles digital audio data with high precision, ensuring low distortion and noise. Technically, the TAS5001 employs advanced digital signal processing to generate PWM signals with minimal jitter and high linearity. It accepts standard digital audio formats and provides the necessary control signals for the external power stage. The device operates from a 3.3V supply and is specified for the industrial temperature range, making it robust for various environments. Typical applications include home theater systems, soundbars, active speakers, and automotive audio systems. The TAS5001's high dynamic range and low distortion make it ideal for applications where audio fidelity is critical. Its digital architecture simplifies system design by eliminating analog pre-amplification stages. When designing with the TAS5001, ensure proper decoupling of the power supply and careful PCB layout to minimize noise coupling. The device requires an external power stage (e.g., TAS5100) and a microcontroller for control, so plan the system interface accordingly.
TAS5026APAG - 6-Ch Digital Audio PWM Processor | TI
The TAS5026APAG is a six-channel digital audio PWM processor from Texas Instruments, part of the PurePath Digital™ family. It integrates a modulator that converts digital audio data into PWM signals for driving external power stages, enabling high-efficiency Class-D amplification. The device operates from a 3V to 3.6V supply and is packaged in a 64-pin TQFP (10x10 mm). It interfaces via I2C and I2S, making it suitable for multi-channel audio systems. 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.
