TAS5010PFBR

Audio Special Purpose Overview

The TAS5010PFBR is a stereo PCM-PWM modulator from the Texas Instruments TAS5000 series, designed for True Digital Audio Amplifier (TDAA) systems. It accepts serial PCM digital audio streams and converts them into 3.3-V PWM audio signals compatible with TAS5100 H-bridge power devices. The device supports 16-, 20-, or 24-bit input data at 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, and 90% power efficiency into an 8-ohm load. It operates on a single 3V to 3.6V 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 multiple serial interfaces: IIS, right/left justified, and DSP formats
• Integrated digital interpolation filter and de-emphasis function
• Hardware mute and clicks/pops reduction capabilities

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 'R' suffix indicates Tape & Reel packaging containing 1000 units per reel. Confirm RoHS compliance and Green status (no Sb/Br). Ensure the design utilizes the TAS5100 family for the power output stage, as the TAS5010 functions strictly as a modulator. Check for MSL Level-2 moisture sensitivity requirements during assembly.

Audio Special Purpose Selection Notes

Select the TAS5010PFBR when a reel-packaged stereo modulator is required for high-efficiency digital audio designs. Compare against the TAS5010PFB if bulk tray packaging is preferred. Ensure the system architecture includes external H-bridges, such as the TAS5100, to complete the TDAA solution. Verify clocking requirements match the desired master or slave mode configuration.

Audio Special Purpose Part Context

This component belongs to the TAS5000 series of True Digital Audio Amplifiers. It serves as the signal processing core that digitizes audio before power amplification. It is typically paired with the TAS5100 power output device to form a complete amplifier system. The PFBR variant specifically denotes the surface-mount TQFP package supplied in a tape and reel format for automated assembly.

Audio Special Purpose Replacement Considerations

TAS5010IPFBG4 is a lead-free, RoHS-compliant equivalent in the same package type. TAS5010PFBRG4 is the reel-packaged version of the lead-free part. No direct functional replacements are documented; the TAS5010 must be used with TAS5100 H-bridges.
