TAS5010PFB

Audio Special Purpose Overview

The TAS5010PFB is a true digital audio amplifier (TDAA) PCM-PWM modulator manufactured by Texas Instruments. It converts serial PCM digital audio streams into 3.3-V PWM signals for driving loudspeakers via external H-bridge power devices like the TAS5100. The device supports 16-, 20-, or 24-bit input data and sampling rates of 44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz, 176.4 kHz, and 192 kHz. Key electrical specifications include a 96-dB dynamic range, THD+N less than 0.08% at 1 kHz with 1 to 30 W RMS output into a 6-Ω load, and 90% power efficiency into an 8-Ω load. It operates on a 3 V to 3.6 V supply within a 48-pin TQFP package.

Audio Special Purpose Feature Summary

• Equibit technology-based PCM-to-PWM modulation with low-jitter internal PLL
• Supports IIS, right/left justified, and DSP serial audio interfaces
• Includes 24-bit linear phase FIR interpolation filter and de-emphasis function
• Mute and clicks/pops reduction capabilities for high-quality audio reproduction

Audio Special Purpose Applications

• DVD-Audio systems
• Home theater amplifiers
• Car audio amplifiers and head units
• Internet music appliances
• Mini/micro component systems

Audio Special Purpose Procurement Notes

Verify the specific suffix against the official datasheet to confirm temperature grade and packaging type. The 'PFB' suffix indicates a commercial temperature range (0°C to 70°C) in a tray package. Ensure the design accounts for the required external components, such as the crystal oscillator and PLL filter capacitors, which are not included in the package.

Audio Special Purpose Selection Notes

Select the TAS5010PFB when a commercial temperature range is sufficient for the application. For automotive or industrial environments requiring extended temperature ranges (-40°C to 85°C), the TAS5010IPFB variant should be selected instead. Both variants share identical functional specifications and pinouts.

Audio Special Purpose Part Context

The TAS5010 is part of the TDAA system, functioning as the digital controller that pairs with the TAS5100 power output stage. This combination allows for cost-effective, high-efficiency digital audio amplification. The device utilizes Equibit technology to minimize distortion while maintaining high power efficiency in stereo configurations.

Audio Special Purpose Replacement Considerations

For extended temperature requirements, use the TAS5010IPFB. Reel-packaged versions are available as TAS5010PFBR. No direct single-chip replacement exists; the TAS5010 must be paired with a compatible PWM power stage like the TAS5100.
