TAS5015PFB - 2-Channel 112dB Digital Audio PWM Processor | TI
料号： TAS5015PFB ✗ 停产TAS5015PFB 概述
A digital audio PWM processor is a specialized audio signal-processing IC that accepts digital audio data and controls power-converter switching to reproduce an analog audio waveform at the speaker or headphone output. Within the product hierarchy, it combines a digital signal processor, a digital audio interface, and a class-D-style PWM power stage, while remaining distinct from conventional analog audio amplifiers. The TAS5015PFB is designed to place amplification and digital processing close to the load, reducing noise susceptibility in sensitive audio paths.
The principal performance features include 112 dB dynamic range, THD+N below 0.01%, 24-bit input-data support, and 176.4 kHz operation. Its 90% efficiency into an 8-ohm load reduces the heat generated during high-output audio playback compared with less efficient amplification approaches. The 48-TQFP (7x7 mm) package provides a defined surface-mount footprint for professional audio, home-theater, communication, and embedded audio equipment.
The device combines digital audio processing with PWM output generation, allowing system-level features such as digital volume control and signal conditioning to be handled inside the amplification stage. This architecture is useful when a product requires high-resolution audio data to remain digital through much of the signal chain. Exact pin assignments, control-register details, thermal limits, and application-specific output-stage requirements should be confirmed against the manufacturer datasheet and pin-description table.
Typical applications include powered speakers, soundbars, home-theater receivers, digital audio racks, professional monitor systems, and embedded audio products. The 2-channel configuration suits stereo systems, while the high dynamic range and low distortion target applications where audible noise or nonlinear distortion would compromise playback quality. The 90% efficiency rating into 8 ohms is particularly relevant to compact systems with limited thermal dissipation.
When designing around TAS5015PFB, preserve the power and ground connections required by the PWM output stage, place output-filter and bypass components close to the package, and account for the heat generated at high output power. Confirm that the selected speaker impedance, supply voltage, output filter, and amplifier configuration match the datasheet guidance before production release.
This page combines the confirmed device specifications, package information, drop-in alternative status, pricing structure, and practical design guidance for engineers evaluating the TAS5015PFB in digital audio amplifier designs.

典型应用
TAS5015PFB 适用于 6 应用s: Powered Stereo Speakers, Home-Theater Soundbar Amplification, Professional Monitor Amplifier, Digital Audio Rack Amplifier, Embedded Multimedia Audio, Communication and Console Audio.
Powered Stereo Speakers
TAS5015PFB fits powered stereo speakers because it combines a 2-channel architecture with 112 dB dynamic range and THD+N below 0.01%. Place the processor near the speaker output stage and feed it with 24-bit I2S audio from a source processor. The listed 90% efficiency into an 8-ohm load helps reduce heat in compact enclosures, while the low-distortion target supports clear playback across demanding audio levels.
推荐
Home-Theater Soundbar Amplification
A soundbar power stage can use TAS5015PFB for efficient 2-channel digital amplification with a compact 48-TQFP (7x7 mm) footprint. The 112 dB dynamic range supports a clean signal path from digital source to loudspeaker, while the less-than-0.01% THD+N specification targets low audible distortion. The I2S interface simplifies connection to digital audio processors, although channel routing and any additional surround channels require separate implementation.
推荐
Professional Monitor Amplifier
TAS5015PFB is appropriate for professional monitor amplification when low distortion and accurate digital playback are priorities. Its 112 dB dynamic range and THD+N below 0.01% align with applications where audible noise or nonlinear distortion can affect monitoring accuracy. The 90% efficiency into an 8-ohm load reduces heat, but the amplifier still needs a suitable output filter, protection strategy, thermal layout, and stable low-noise supply.
推荐
Digital Audio Rack Amplifier
Rack-mounted stereo amplifier modules can benefit from TAS5015PFB because the digital audio input avoids an early analog conversion stage and the 2-channel device supports standard left-right routing. The 48-TQFP package is compact, while 90% efficiency into an 8-ohm load helps manage thermal loading in sustained operation. System integrators should validate channel mapping, control behavior, output filtering, fault handling, and amplifier protection in the finished enclosure.
推荐
Embedded Multimedia Audio
TAS5015PFB can serve embedded multimedia products that retain a 24-bit digital audio path and need efficient stereo output amplification. Its I2S interface connects to embedded audio engines, and the stated 176.4 kHz capability supports high-rate digital audio workflows. The 3 V to 3.6 V supply range suits compact embedded systems, but designers must carefully manage grounding, clocking, output filters, and thermal conditions around the 48-TQFP package.
推荐
Communication and Console Audio
TAS5015PFB is suitable for communication consoles and audio products requiring two amplified channels from a digital source. The 112 dB dynamic range, sub-0.01% THD+N target, and efficient 8-ohm output behavior support clear speech and music reproduction. Firmware and hardware teams should confirm the supported I2S clocking mode, required control interface, output latency expectations, and protection requirements before integrating the device.

关键差异点
- High specified dynamic range （对比 TAS5000PFB)

- High efficiency into an 8-ohm load （对比 TAS5000PFB)
- High-resolution digital audio capability （对比 TAS5000PFB)
设计说明
TAS5015PFB operates from 3 V to 3.6 V. Provide a stable regulator with low ripple and adequate transient response, and place the required bypass capacitors close to the supply pins. The public product listing confirms the supply range but does not specify the exact capacitor network, so use the manufacturer application circuit as the reference implementation.
The listed 90% efficiency into an 8-ohm load reduces heat, but high-output stereo operation can still raise junction temperature. Estimate dissipation from the worst-case output power, supply voltage, load tolerance, and efficiency, then size exposed copper around the 48-TQFP package. Confirm the package thermal data and maximum operating temperature in the datasheet before defining the enclosure airflow strategy.
Keep digital audio, control, power, and ground paths organized so that switching currents do not cross sensitive signal areas. Follow the manufacturer layout and output-filter recommendations for the 48-TQFP device, particularly component placement around supply pins and the PWM output network. Validate the completed PCB for audio noise, EMI, channel crosstalk, and thermal performance.
Do not assume that any 48-TQFP audio processor is pin-compatible. Check the complete pin-description table, supply limits, I2S timing, control interface, output configuration, and protection requirements against the TAS5015PFB datasheet. The listed 176.4 kHz rate and 24-bit input capability also require a compatible source, clock arrangement, and output network.
